yes, they charge 20% fee, but when you look at ebay and ebay listing fees, final value fees, paypal fees then the time to scan a card, list a card, send invoices, buy a bubble mailer and packing supplies, pack the card, leave feedback, drive to the post office, stand in line, pay the postage, mail the item, track the item, and deal with customers, etc, etc..it is well worth the 20%, i think all of the ebay and paypal fees are probably close to 20%. with comc, you box up your cards, ship them and then forget about them and just let them sit there and make you money. no processing, no shipping, just collecting your money! it also saves me for having to store tens of thousands of cards. ill send them 1,000 cards or so to see how easy it is, it seems to good to be true, but we will see how it works out.
