How Not to Buy Manga

My spending habit's gotten me into a bit of a problem again... I have an issue of routine, leading to me not being able to drop a series once I've starting buying it no matter what. Also, I like to pre-order things WAY in advance, so my latest amazon order was gigantic.

Goddamn, Mitsu!
I still haven't even finished reading my manga from months and months ago.
I'm really stupid.
NEVER buy manga in bulk like this. My only savior is that since it's pre-order the payments only go through after it comes out. But when you order manga in bulk, just as anything else, you never, ever, get around to actually reading them all.
