Well, I don't know what worked for me, but when I tried my third credit card, it went through. I thought maybe it was the card I was using, but usually that will give you a message that the card is invalid or something. Not a Page Not Found error. Whatever it was, the third time was a charm, my Visa went through that time, and I got the item I was trying to buy. I hope this snag will get worked out or I won't be buying things from the MarketPlace anymore. Too frustrating. Also, once again, whoever moderates the stores, please indicate somewhere on the site which credit cards are accepted. I never know which one to use. I have almost every kind of card except American Express (I won't touch that one with a ten-foot pole). It would be nice to know what I can or can't use. Melanie
