Yeah, those prices are per 10 bullets, but not all clips are in multiples of 10s, so the OCD part of me has to buy them in quantities that are both a multiple of 10 and a multiple of the clip size. So like for my Ingram Smartgun X, I have to buy at least 160 bullets at a time, because the clip size is 32, and that's the minimum I can buy without having any bullets left over. I know, its ridiculous, since you might not use an entire clip in a run and thus would end up having bullets left over anyways, but I can't help it.
