Have been using Ziffit for some time now, they were always better than other we buy sites and since the demise of Momox they are my only go to site. Prices could always be better but they are prompt, efficient and reliable, the more you use them the better the system seems to work. DPD couriers operate in the area and are regular lads so no real problems there. They take around a third of my reads, the rest I just tend to give away, I rate them 4.5 but thats only because I believe good quality books in mint condition should be valued higher, if they did this I would give them a 5.
