I always assumed the reason the RZ certificates don't apply to online is because they have to pay for the free shipping when you order online, and obviously they'd rather save themselves that expense by forcing you to come to the store, although I'm sure it does help them that fewer certificates are redeemed due to the inconvenience of having to go to the store. I do so much online shopping I actually get into a bit of a panic trying to browse a store, so I always check what's in stock before I go there and get in and out as fast as I can, so they're definitely not getting any extra purchases off me by having me in the store if that's what they're thinking. Anyway, so far I've had no problem redeeming all my certificates, and they've actually given me $85 total in certificates, even though I was only supposed to earn $55: I think they accidentally doubled a few of my 800-point pre-order bonuses when they introduced the Gamers Club, lol. I love Best Buy!
