I suppose it could be Google checkout, the vendor or something else in between, but the bottom line is that buying apps over the Droid isn't secure.
It would be helpful if I could contact Google for help, but they don't provide any means (that I can find) to do that.
Every time I buy something from the Market, my credit card company calls me (I have ID Theft Protection for all my cards) - they ask if I bought something, verify, etc.
I think that it's something intrinsic to the market, i.e., there's fraud going on somewhere in the loop and a good card issuer (I have Citibank) will monitor the activity.
Google really needs to clean this up - when you combine this with the pathetic organization of the market it's a much less satisfactory experience than, say the Apple store.
