I told my local comic shop about the sale Diamond is having. I told them if I'd take all I can get at the $25 to $30 range. I promised to buy at least one book a week, on the weeks that I wasn't already gettting other new releases of other collected editions. Of course they said "yes." It looks like I'll be having a very Spirited end of summer.
Oh, I picked up volumes 12 and 14 on eBay by saving my searches, and getting an automated email whrnever they were listed. Got them kind of cheap, too.
