Look, I understand there are scammers out there and there will always be, and I understand requiring confirmation for purchases going over a "significant" sum, but this is just stupid and increasingly wasteful of the user's time to require you to confirm every single purchase or sale you are going to make when their price is measured in a few cents. Especially so when their servers can't even seem to handle the bandwidth and in the time you spend trying to confirm your purchase of a whopping 5 cents the item is already gone. The use of common sense is not outlawed and it is generally even encouraged.
