Zapper.co.uk is like musicmagpie.co.uk but seemingly accept books as well as CDs, DVDs and games. Great! You may think. Finally a chance to get rid of all those old paperbacks on the shelf gathering dust? My advice would be: don't bother.
I tired 15 books ranging in type from paperback novels through to travel to sociology to music books. All except 2 were rejected as they weren't interested in them. Of the 2 that were accepted, they were willing to offer a total of 50p for them.
I also tried a few CDs and in general they would offer less than musicmagpie.co.uk
I gave up after a while as there is a minimum requirement for the value of books, etc... until you can send. This is £10 and at the rate I was going I probably wouldn't have got there.
The site says it accepts 20% of all barcoded books but from my experience and the trial I did, it seems to be alot less.
I'd suggest not wasting your time and energy on this one.
