I just canceled my card.  Because of a warning thread over at DAZ, I checked my activity online, and there was a ten cent charge in Oregon, when I called the bank, they told me about several other "probing" type charges.   I bought some stuff here this week, and when I checked out, I filled out the credit card info, hit submit, and the page flashed and went back to the beginning of the checkout process.  I tried again and it worked that time.  It worked like the regular checkout process, right up to the end.  Don't know that it was someone intercepting the order somehow, but it kind of looks that way.  The only other online orders I made were to Amazon and Paypal.
