I was in that topic at the same time (I made a purchase 10 minutes before you posted the "I'll take it". I specifically remember your post saying "as per PM", because one of the books you asked for was one I wavered on and decided against, and also I remember thinking how maybe I should have worked out lower prices before committing to buy.
The "as per possible PM" or whatever it says now sticks out a lot, it's actually what made me notice that posts could be edited with the option to not mark it as edited.
Vindicated! Thank you!!
