I've been lucky so far in getting my parcels delivered, either from Q, Amazon etc. I've just ordered something today so hopefully will get it in time for Christmas.
I have been enjoying watching people doing it on FB, it's in a good cause and it's made me laugh. My husband is in Texas and he will be doing his challenge later. At least it will be warm out there!
I've had to send stuff back and they now tell you to put it in writing (email) but will make a note on your records if you have told them on the phone. I always write the total amount including P&P on the returns form and so far have had no problems.
