Maybe I'm just extra crabby this morning, but I'm kinda pissed that I went to my account and found I was opted into "quick buy" without my knowledge.
Since their regular prices are pretty much always higher than buying elsewhere I only buy from Kobo when a coupon is available so "quick buy" holds zero interest for me. Instead of adding this they should have added a cart option which is something a lot of people have actually asked for.
