I think QVC need to change their MBG so that items have to be sent back in the same condition they were sent out. It seems pretty rum to me that someone will wear something out, literally, for a month and return it knowing full well that's what they were going to do when they bought it. No shop would accept that. I used to run catalogues back in the pre-tv shopping days and they were very clear that returns had to be sent back as they were received. That helps keep prices down for everyone in the long run.
I hear what you're saying Moth, but most of the stuff I buy is beauty products, so I HAVE to try it to know whether it is going to live up to it's promises/suit my skin or not. If QVC didn't offer this then I'd probably only buy my 'tried and tested' ranges that you can't get elsewhere in the UK, and certainly wouldn't take a chance on anything new.
I often do use a cream or whatever for pretty much the full month, as (is often quoted by the presenters) you need to give these things a good test run to find out if they will work for you.
Obviously clothing etc is different but again sometimes you can't tell if an item is really what you want unless it's worn in the 'real world' - not just tried on at home. For me this is particularly true of footwear, I only know if shoes/boots are going to be comfy if I can wear them for a full day, including going outside and driving in them. If QVC didn't offer this then I wouldn't be buying from them.
With the Centigrade coat I bought, not sure if someone had actually worn it (slept in it??) before, but from reading the other reviews on QVC which were ALL terrible, think it was new and unworn - just absolutely hideous quality!
I do appreciate that the system is open to abuse by people who just want a bag, pair of shoes etc to wear to a special event and buy with the full intention of returning, but not sure if there is a way round this, the 30 day 'no quibble' MGB is one of QVC's key selling points, & think they would lose a lot of custom if it was taken away or changed.
