This might be a little far for you, but in LA they have a huge women's consignment sale in a warehouse a few times per year. All you have to do is tag your item and you get to set your own price. Of course, there is a fee or commission charge the company organizing it takes, but I hear its worth it.

I almost went to that sale this year but I had just fired my #1 client and decided I couldn't afford it.
I'd try consigning too. I bet Upland has some decent stores, and if not, you might do better in the Pasadena area. It would be worth a drive if they'd offer you more moneys.
