Ziffit tend to offer the best price on a wider range of items compared to their rivals and I've used them many times with stuff that doesn't sell elsewhere. The site is easy to use and they've recognise pretty much everything I've ever entered, including old and obscure books. The process is straightforward and I chose to use the InPost drop-off, which was a doddle - just rock up with your QR code/number, type it in and follow the instructions on screen! You get a QR code on successful completion too. All the items I sent were accepted and paid in full as per the original agreement. Payment was a bit slow this time, probably as it was Christmas, but I eventually got a PayPal message saying I'd been paid.
