What should I do with 300+ empty beer bottles?

Most of these bottles—mostly from local beverage brands or generic soda distributors—are just sitting around. They’d be worth $0.42 if I actually had the original receipts, but since I don't, and I have zero use for this much empty packaging, they're just cluttering things up. Anyone have a lead on where I could sell them, or perhaps a more productive way to repurpose them?

Since this is my first post here—so, moderators, please feel free to move this to a more appropriate sub-forum if you think it's misplaced—I didn't see a perfect spot for it.

What, has nobody ever been so lonely they downed 300 beers and lost track of the bill? :-D
