This is so crazy. I got the revised offer last night, too.
It would be disappointing enough if they had just changed from a gift card to a coupon, but then to say the initial purchases must be from a specific list makes the offer useless to me. Only a couple of books on the list were of even marginal interest, and I'm certainly not going to spend $55 on them just to get a 30% off coupon, when Kobo offers plenty of coupons without prerequirements anyway. They took away all the incentive to go on a shopping spree.
