How hard is it to find some fricken zippers?!

[agirlonthewall.livejournal.com]

I've been on a mission for the past several months to find your basic black and silver YKK zippers (the ones that are on, like, every Hot Topic product ever made), but to no avail. I've checked JoAnne's, Wal-Mart, you name it, but I can't find them anywhere. Do any of you fine ladies know of a place online where I can order various lengths for a decent price? Thank you bundles.
