I haven't had experience buying the accounts but I used to buy the vouchers at deep discounts that people would sell here. I've had good and bad experience. Use fast because people will cancel. I had a helicopter ride scheduled once and when I arrived for my appointment, they told me it had been cancelled for some reason. I thought totally I was going to have to leave without the ride but I just played really dumb and they just ended up letting us go. I've had restaurant ones not work and just had to pay full price. It sucks that with the vouchers there isn't really a way to check them. With the accounts at least you'd have an idea when you went to redeem that everything still looked good.
