Well, they are against PayPal, GPA, Credit Cards and all other services. They DON'T want to do anything with any kinds of fees. They always put 3% fee on the buyers so they don't want to pay the credit card fees. That was a long time ago. They were ahead of the games before CC, Heritage and all other auction companies recently decided to put 3% fee on the buyer's invoice if they use the credit cards. That was how I learned from Comiclink and I have paid them with my personal checks for over 12 years. Sometimes, I use my credit cards but I still pay 3% charge fee.
