Best way to sell all of these books?

Actually, if you do a search on COMPLETED items on eBay, you can see if an item has sold, and what price it sold for. So there’s one way to check for the market value, or at least the approximate market value.

I think I’m going to take this route; I always have extra time on my hands this time of year. The post office is about 7 miles away, which is the nearest town so I have to go right by it anyways.

Out of curiousity, what game?

If you’re interested in selling them online, you could also contact Thriftbooks.com - they have a whole slew of used books that they sell through lots of individual sellers - their prices are pretty universally low, but (to me) they have a much better organizational structure than Amazon Marketplace does. Might be worth checking out.

(full disclosure fyi - I have three like-new textbooks/scholarly nonfiction for sale in Amazon marketplace, all for significantly less than my competition has them listed, and have sold none of them in the 6 months they’ve been listed. It’s sad.)

Psi 5 Trading Company. I found a couple of old copies, bought them both (at six bucks each) and now I’m waiting for them to arrive to test them out. In fact, I’ve got a “Wanted to buy” thread in Marketplace, which I just updated.
