"All transactions are subject to a three percent (3%) Buyer’s Premium which is in addition to the purchase price, which premium may be fully discounted if the total amount due is received by COMICLINK within 7 days of the close of an auction or a final exchange sale confirmation, and under certain payment terms, such as check, money order, or bank wire."
Now I guess I'll go back and look at my past receipts. Normally I pay by cashiers check the next day. Seems like I've never had a purchase that doesn't include the 3%
OK, I just went back and looked at my last Clink purchase, and I find that they charged me the 3% because I used a credit card. My dumb fault entirely. Sorry, Clink and @Gotham Kid
