Another option is to list them at www.glyde.com. You can also sell movies and video games at Glyde, and the set-up of the site makes it very, very easy. You list the items you have for sale and their condition. Glyde suggests pricing and shows how much you would earn from the sale. Typically it isn’t much, because of shipping costs, but if you have high-demand things you could do OK. When someone buys something of yours, Glyde sends you an addressed, prepaid mailer. You put the item in the mailer, drop it into your mailbox, and get paid when the buyer receives it. The money you make from each sale is deposited into your Glyde account. You can then have it transferred to a Paypal account, mailed to you as a check, or use it as credit to buy something you want at Glyde.
What I like about Glyde is the simplicity. I don’t have to worry about having packing materials, buying postage, or going to the post office. The site is extremely easy to use and it takes only seconds to list items.
The downside is the wait for items to sell. I’ve had books for sale on Glyde for months. When a few things sell, I end up using whatever money I’ve earned to get another book or a game for the kids.
There’s also a site called swap.com where you trade books, games, and DVDs directly with other people. It’s a bit more involved because you have to pack up and ship things yourself, but you can print postage right from the site. If someone fails to ship you an item in a trade swap.com will send you the item so the risk with trading is quite small. You don’t make any money, but you get to pass on things you no longer want to get things you do want.
That being said, I typically just drop used books at Goodwill because anything else is too much effort or involves too much waiting. :)
