well, it was very close, but i managed to resist. (ouf !) this weekend i got so far as to go through my entire wishlist and transfer over the books i most wanted to my cart, and admire the savings / refund i would earn. but then i looked at my bookshelf, and all the books i bought during the last sale which i haven't read yet, and i decided that i should probably get a grip and finish them first.
after all, there will always be another sale.
(and i probably won't manage to muster that kind of self-restraint twice in a row).
