Periodically, I list a book or two on Half.com, usually something I got for free somewhere or something found while cleaning the house that we don't want or need. I've had mixed results, but since there's no cost for listing, I've got nothing to lose. I've sold quite a few over the years.

Lately, I've been getting these short online medical surveys that offer a selection of items to choose from as a reward. I don't want or need any of the items but one choice is a nice medical dictionary, so I've selected that. So far, I've gotten 3 of them. I sold the first one a few weeks back. The 2nd one sold today. I haven't listed the 3rd as I just received it yesterday, but I'll definitely list it now that I see how quickly the first 2 sold. And I think I have at least one more coming to me. I got $8.99 for the first and $7.98 for the second. I always make sure mine is the lowest priced listing for that item.

I also got a promotional set of diabetic cookbooks. I listed 2 of them yesterday and one sold today. I got $7.99 for that one.

So that's $25.00 for 3 books that cost me nothing. Not a bad deal at all. I'll take it.
