I am in the long drawn out process of reducing a very large book collection as the space is needed for other things. All the books are in excellent condition and are generally quite specialized. Many of them were difficult to obtain originally and It would be a great waste if they were simply discarded. The prices offered by Ziffit, although not high, are reasonable and not having to pay any delivery charges makes a very big and positive difference. It is easy to use the Ziffit website and the arrangement whereby you can simply take your box to a local shop for collection is very good. Payment is prompt.
