Bottle-cap mulch

I love an unusual mulch. Heck, I love an unusual anything.

I bought a massive sack full of these cork-lined unused bottle caps from a yard sale a few months ago and the first thing I did with them was dump some of them into my Pencil Cactus' pot as a cool and useful mulch. And then Dan told me they were worth some serious scratch so I'm testing the waters. I have listed a few on eBay. If they sell well, I'll take them out of my Euphorbia's nest, if not... they stay.
