There has been a lot of anst in the forums lately over the concept of "sniping", and there seems to be a misconception floating around that under-valued auctions should only be bought by certain people, or for certain purposes. But just like the community gardens, the auctions are available to everyone. When you post something up for auction, you get to choose the price, and that's it -- you don't get to choose who buys it, or what they do with it.
I've got some things to say about setting the best price, but I'll save that for another thread!
