I've been selling surplus books/media to Ziffit for a while and been impressed by their system and service. My latest trade took a while to arrive (bank holidays) but like the others was promptly processed and payment by my preferred method issued. The dpd collection is really good too- giving a one hour time slot so you don't need to hang around waiting for them. Only had problems with a Ziffit trade once or twice and their customer service people sorted it pretty soon. I've got another box of unwanted (ex-E Bay stock) to go and am sure Ziffit will handle that well too. Recommended.
