If you are willing to use "seconds" (sticks that have slight visual or other blemishes), Vater sells bulk packs of their "Goodwood" sticks, $40USD for 12 pairs. I'm considering getting a pack of these for everyday practice, and using the regular sticks for gigs only. I don't chew up sticks but the tips get flattened out fairly quickly.

Incidentally, what does everyone do with older sticks that are still OK, but not up to your normal standard, or sticks that you tried out and didn't like? I put mine in a big box that I've had for years but I don't know what to do with them.
