I used Click and Buy one time and was overcharged. It was only by a few cents so I didn't care. But it seemed shady.

Now I just buy crysta in the exact amount I need(ed) straight from my visa card. Never any issue. Still, I'm not saying its easy. The problem is, when it doesn't work - you're pretty much screwed.

Ever have this problem buying from Amazon??? NOPE. SE needs to get their payment crap together.
