I have never seen the appeal. They do sometimes come with EZP which may be attractive but I always want a special price or free postage and those hot picks are like hens' teeth.
I just looked on their FB page to check out this change in hot picks and couldn't see it but instead saw a reference to a site called resolver.co.uk which helps you if you have problems with Q. I don't have time to check it out but I think it might tell you clearly if Q can refuse postage and whatnot cos that is the first complaint on the item. Q sent the wrong item and are refusing to pay costs of the return. Typical. Anyway thought I would mention this site in case it is useful.
