I am currently adapting our system to start supporting graded cards and other encased cards. These cards are going to take longer for us to process, they will use significantly more storage space, they will cost more to insure, and they will cost more to ship.
We are planning to charge $1 for the processing fee and $1 for shipping. Normal raw cards will stay $0.20 for processing and $0.20 for shipping, but we will also bump the maximum shipping fee from $20 up to $30.
Let me know what you think about these proposed fees.
