I've never had a problem with them until the other week. They sent me Scott Pilgrim 6 signed (as requested) but damaged (not requested). I'm abit OCD so I emailed them and they said that they'd be happy to replace it, and they had put one aside for me.
Got my replacement today - an unsigned book 1 which I already have! Not impressed. I've just checked their website and they dont have any left. I will be fuming if they dont still have one for me. Literally fuming.
