The coupons are not what they are supposed to be. Even when a coupon is valid, there may be some hidden restrictions you won't be aware of if you just register the coupon through their "Manage Coupons" option. You would expect once you did that, all possible restrictions would be listed in the "Terms and Conditions" link for that coupon... And you would be wrong! (at least, sometimes). I tried using a coupon that by all research, had not any special restrictions. Again, WRONG! It seems to only apply to watches, though no such restriction was listed anywhere! So, before you count on a coupon, send them an email requesting full disclosure. Yeah, I know, you should have not do that, but this is their crappy operation.
