I have been trading with ziffit for years, most prices offered are pretty low but are better than other traders and payments are usually quick but not over this christmas which is understandable. I have had quite a few problems over the years, it can take a few weeks to sell 10 books, they accept the first 4 then say they can't take the others at this time even though I put in over 800 books. Now I keep getting told that certain books were not received which I know for certain were in the box so I send them emails to say they are wrong and they soon rectify it. The last trade they accepted 26 items rather quickly but when I went to complete the order they said some items had to be taken off and left me with 10 items to send which I wasn't too pleased about. Having said all that they are still the best company to trade with.
