I have done four trades with Webuybooks and have been relatively impressed. The first trade I needed to call up a very helpful lady on the help desk as I queried the length of time to process. I was told a claim would be put against my hermes and I would be credited by cob the next day. I use ziffit and snapper aswell. I do find that 70 per cent of books ziiffit outpay . I do think turn around times are better with Webuybooks. .my preference with ziffit is the fact I don't need to print anything out ...I can write surname ,Ziffit and code provided on the box and that does the trick . I would also say the Isin directory database slightly better with Ziffit. I think your delete function is far better than ziffit. Far too many times I delete something from ziffit by mistake... I have done 10 trades with Ziffit , 4 with Webuybooks and 1 with Snapper.. I am impressed with your communication and resolution I think you should apply a bonus percentage to repeat customers instead of a 10 percent for weekend trades . An incentive the more trades the better percentage reward applied. I don't want to have to scramble around looking for promotion codes . I hope this helps ...just my honest feedback.. thanks David
