What's the best site to sell second hand books, where you get one quote and they collect them altogether?

I know music magpie do it but is there one that pays a bit more than the others?
I can't be arsed selling individually in eBay etc and would like a few pounds instead of giving to charity shop.
Thanks

Ziffit? You generally get an additional 10% on your first transaction with them. Generally get about 20p-£1 per book. Can drop off in one package & they'll collect it for you. Not amazing rates but a convenient way to get rid of loads at once
