Will be interesting to see whether following the episode Q decide to alter their policy. Of course I am not 'clairvoyent' but I wonder if it is to do with the cost of returning items. I mean how many times on this forum and on the reviews for the items do people complain (and justifyably in today's market), bemoan at the cost or return postage. Given how other companies operate and the fact that they actually charge postage at all (and only a measly 1/2 reduction for 2nd and subsequent), but the 'kick in the teeth' is that if you don't like it you can return, some will decide not to bother as given the item may have been 'relatively low', in the first place, may find it is not worth the effort, of course therefore in Q's eyes it will be another 'satisfactory customer' and their sales rate high, in reality of course, this is a long way from the truth.
No, it is time Q UK do what Q America do and allow Paypal as a payment method as at least this way, some of the postage return costs can be paid for!
