buttons!

[themollylamaxx.livejournal.com]

About a week ago I made a post about making buttons. Someone suggested our school might have a button maker, and after a few days of searching we found one in the elementary building (we have a elem, middle, and high school all on one campus). Now the problem is, we cant find buttons for it. The machine is called a bade-a-matic II, and we don't know what size it is. We've been to michaels and ace, along with a few other craft stores, and all they have are the snap buttons which would be way too expansive because we have a lot to make. So my question is, where do I find button shells online or in stores that aren't extremely expensive. If its online, the place would have to have fast shipping because we need them as soon as possible!

thanks in advance
