Phoenix - Sucraft mentioned Ziffit.
I didn't get rid of hardbacks, including four Terry Pratchett's from the 90s that are in top condition (wonder if my boys ever read them ) so I went on the Ziffit site and it's great. You either download the app and scan the bar code or type in the number under the barcode.
I got off to a great start and was offered £7.95 for one of the books and nothing for the rest! You can also do the same with CDs, DVDs & Games.
I'm hoping GS(11) will want the Pratchett's, one of which is signed.
