ok, they're all there but someone trying to make a purchase said she tried American Express and MasterCard but it wouldn't take them. The credit cards are on the list of course as an option so I just didn't know why they wouldn't work unless it was a problem with her own credit cards. I'll assume based on your answer then that if they show on the dropdown, the system is set up to accept them. There have been some orders with MasterCard, I couldn't find any with American Express but I did notice almost all were with Visa, so I was inclined to believe her...for a moment.
