This is so entertaining and interesting... and frightening. My late father was a published Professor of Computer and Information Sciences and this would have fascinated him. Well done.
I have purchased a lot of stuff on cardshark. I mean, a lot. Good deals are easy to find, and I'd rather pay $0.05 per common on cardshark than $0.49 of SCG or T&T.
I sold off 2 extra Grindstones at $17ea. The buyer was charged $1.30 for shipping (which goes up depending on how many cards are in the order). After fees, I ended up with $30.10 of the $35.30.

Hope this helps.
