My main point was against your statement that the items associated with donation levels weren't worth it. I'm saying that they won't be because the people looking for money aren't looking to give away/sell their stuff. If they were they'd do so in their online shops. It's not meant to be an exact equivalent of the money you give, it's just a way for the asker to say thank you with items.
Take Pretty Things Peepshow. They did a kickstarter so that they could buy a new touring bus since the vehicle that they were using bit the dust. Sure they had 'prizes' like posters, nipple pasties, classes, or would do a show at a wedding, but the main reason that people donated was because they wanted PTP to keep touring.
I'm not saying this for the original posters sake since I don't really see the point of it, but for kickstarters in general.
