wait, what? that's super duper shady as shit. the darkest of dark patterns, and probably violates something more than my feelings. there's been many a times i've gotten all the way to the review and just before hitting confirm/submit/buy/purchase/complete/etc, i've backed out because I had forgotten something or decided to check another site just to be sure. luckily, nothing like this has ever happened to me.

They could very well store your card information even if they don't fraudulently charge you outright. They could even legitimize this action under the guise of server-side credit card number validation.

That's different than charging though. A lot different. There's no real way of knowing what goes on under the hood when putting your info into a web/app form like this, but if I was charged for something without pressing the actual buy button then "Houston, we have a problem".

True, that would certainly be not as worse and downright illegal as charging. It still seems very slimy, though -- why are you storing my CC details when I never actually made a purchase on your site?
