I say buy this product while you can if it's something you're interested in because this concept won't be around long. I sincerely doubt it's 100% legal.
Just think, this kind of thing can pop up everywhere if it's allowed. I might as well go out and buy a bunch of collectible coins, and a hand full of very rare, very expensive ones, package them all up, and sell to people as a grab bag style offering, making myself an unlimited amount of cash. That's what this Razor Rookie Retro product is, and if/when the Attorney Generals catch wind of it, it will no longer be available.
This is not a new concept, it's just a relatively new concept for a card company to do it. Programs like this have been shut down many times. He might get away with this one, but sometime in the future, this will cease.
