Test Auctions & Win a Shopping Spree

If you haven’t tried out our new auction system. Now is a great time to kick the tires. We have more than 400 auctions that end tomorrow, and we will be starting hundreds more that end on December 25th.

COMC auctions are refreshingly simple. When you win auctions, the items transfer into your account within minutes of the auction ending. If you don’t have enough store credit in your account when the auction closes, that is OK. As soon as your account has sufficient store credit, the items will automatically transfer into your account within seconds. And as always, you get flat rate shipping on unlimited items, or you can put items you win back up for sale instantly.

Win a Boxing Day Shopping Spree
Go test out placing a bid. On December 26th, we will be issuing $1,000 worth of shopping sprees. 50 different users that have placed bids will win a $20 Boxing Day Shopping Spree. You will get one entry for every different auction you bid on, and you will also get one entry for every dollar you spend on auctions that you win.

We will be taking the site down from 11PM PST to 5AM PST to address several of these issues. Since many of you were unable to accomplish some of the tasks because you were so successful at stressing out the server, I will see what we can do about awarding some extra prizes for those of you that hit errors.

Historical Suggested Prices

About a month ago we rolled out our first version of Suggested Prices. Based on the feedback of many COMC customers, we have revamped our model and just released v2 of our BETA Suggested Prices. This time we have included some charts to help you analyze our suggestions.
SalesData

For those of you not familiar with our Suggested Prices, you can learn more here.

As I mentioned in my original announcement video, we have the cleanest set of historical sales data ever complied. This gives us a unique opportunity to provide relevant price suggestions without having to factor in so many variables.

Our Suggested Prices are still in BETA testing. We want your feedback. Here are some important details about the COMC Suggested Prices.

Data Sources
We only use COMC historical sales data. We do not factor in sales from any other websites, and we do not use any other guides or services. All of the COMC Suggested Prices are based on a mathematical model that I designed and implemented. We have made no attempt to replicate or mimic any other guides or services. We fully expect that you will find our Price Suggestions to be very different from other guides or services. My goal was to boil down a bunch of numbers into a few easily digestible suggestions. Here are the goals I tried to achieve and what numbers went into generating each suggestion.

  • Suggested Retail Price (SRP): The SRP is intended to be a fair asking price for a retail store. This is currently just a standard markup on our Suggested List Price. We figure it is fair to expect to pay a little premium in order to see the item in-person before buying.
  • Suggested List Price (SLP): The goal of the SLP is to be a reasonable List Price that a seller might use to put an item up for sale on COMC. The SLP is based on the total price that buyers actually paid to take possession of their items. That means we only factor in items that were sold and shipped when generating the SLP. While this is based on confirmed sales, it is not an average. An average or median would leave no room for buyers to make offers without constantly driving the price down. Instead we have factored in a little bit of room for people to negotiate prices.
  • Suggested Wholesale Price (SWP): The SWP is intended to represent the price that sellers can reasonably target if they are trying to sell their item quickly. Often buyers in this price range are purchasing with the intent to resell. That is why we refer to this as the “wholesale” price. This factors in all sales on the site, but we treat port sales and other large offers with a grain of salt.

Chart Elements
Bar charts have been added to the top right corner of each card details page. Bar charts, with additional lines representing suggested prices, have been added to the popup you see when you click on card prices. The bar chart represents the number of items sold in a given quarter (3 month period) for that particular card. The rightmost bar represents the sales for the current quarter, which will just be a portion of a quarter. The sales from all the different conditions and grades are lumped together in the bar chart. The lines represent the SRP, SLP, and SWP. The points are measured on the last day of the given quarter. The rightmost point on the line represents the current Suggested Price. The chart shows the last 15 full quarters and the current quarter.

Partial Sales Data
Because the rightmost bar represents only a portion of a quarter, it will often appear lower than other bars. This does not typically mean that sales have been decreasing for an item. It more often means, that we are simply in the middle of a quarter and we are still adding to the total sales for that quarter.

Charts with No Lines
Some listings do not have enough historical data for us to generate a Suggested Price. You might even find some listings that used to have Suggested Prices, but they no longer have suggestions. This is because we consider older historical sales as less relevant. If the total relevance that was factored into a suggestion is too low we discard the suggestion. Years ago, this data was more relevant and our model may have been able to make older suggestions.

Extrapolation
The current model only looks at historical sales of the exact same item in the same condition or grade. Later this fall we will begin factoring in similar products and conditions. This will help enable us to make price suggestions for items such as printing plates. While we may have never sold a particular printing plate, we may have sold a different color of that plate or other printing plates of that player or other printing plates from that set. These data points can help us make recommendations for items that we haven’t sold yet.

Vintage Suggested Prices
We know that vintage card prices are very condition sensitive. Please take all pre-1980 COMC Price Suggestions with a grain of salt. Because we have not factored in detailed condition ratings, we may choose to completely turn off these suggestions if we find that they are too misleading.

Frequency of Updates
We re-run our analysis every night. If a player has a great game, the sales from today will be factored into tomorrow’s model.

Historical Suggestions
You might wonder how it is possible for us to offer Suggested Prices that go back 4 years when we only started offering these suggestions a month ago, and I have to say, that is very perceptive of you. You see, I have been watching a lot of YouTube videos about Astrophysics, and I recently stayed at a Holiday Inn Express. As a result I was able to find two colliding black holes and hitched a ride going faster than the speed of light in order to run the model at different points in time over the past several years.

Actually, I just designed the mathematical model so that I can plug in any point it time and it will generated the suggestions based on the historical data before that point.

Changes from V1
We got feedback that the Suggested Retail Price from our first version of Suggested Prices was too inflated. This feedback has been incorporated into the new mathematical model we use for the new version of COMC Suggested Prices. If you notice an SRP is lower than what you remembered, that doesn’t necessarily mean that the value is decreasing. The entire model was adjusted. It is best to refer to our charts to understand the direction the market might be heading.

Feedback Wanted
Please go play with the site, find interesting data, and discuss it in the comments below and on other forums. We will be monitoring the discussion to find ways to improve our suggestions.

New Search is Live + Free Promotions & Free Shipping

The new search infrastructure that I mentioned in my last video is live, and it is now the default search. To compare it to our old search, you can simply check or un-check the Use New BETA Search checkbox. Note, the old search results may be a couple days out of date. We are measuring how fast updates appear with the new search infrastructure. If there are lots of promotions or other activity, it looks like it might take a couple hours to reflect all of the new prices.

UseNewBETASearchWe want to stress test the new search infrastructure, so please try it out. As an incentive, we are allowing sellers to run FREE Sale promotions for the next week, and we are also offering free shipping on orders of 20 or more items. Shipment requests must be submitted by midnight PST Wednesday, July 23rd. Items purchased from Advanced Reselling Mode are only eligible for a $3 shipping discount.

New Search Features
You will noticed that the filtering options offered on the left have changed a bit with the new infrastructure. It is now a LOT easier for us to add new search related features. You can expect to see new features light up from time to time over the next several months. This is some of the ground work for our new SRP.

Search Performance
Search results are consistently snappy. No more really slow searches. Also, the new search infrastructure has the ability to automatically scale up to support any level of demand (in theory). That is what we want you to test.

For the first time we have decoupled the search functionality from the rest of the website. This means that the database that tracks asking prices and ownership of items is no longer bogged down with all of the search requests. This is a big deal. Last Black Friday our database server was basically maxed out the entire weekend. Now we should be able to support more than 10 times the traffic and still have great performance.

Feedback
Let us know what you think of the new search. What search features would you like us to add?
