If you signed up for Listia below, hopefully you made your first bid/purchase, generally for My Coke Rewards points.
If you have burned through your points already, there are a couple of ways to boost your balance. First, you can get a quick 100 points by listing your first auction. You can auction anything at this site. Well, I think it has to be legal, but you know what I mean. In other words, don't put a lot of effort into this one.
You can also do special offers for points. There's a lot of surveys, trials, etc., but there are some freebies.
Note: In the spirit of full disclosure, you should know that I do get referral points when you list your first auction.
