I agree with Lacuna -- try returning some items? That could help.

Also, my sister likes to sell things on Poshmark all the time. You can sell things there that you can't return. I think it's only for clothing and accessories, though, but she gets LOTS of people buying the stuff she sells.

There is also Amazon Marketplace. I've bought tons of stuff there. Not sure about eBay since that can be hit or miss.
