Last year customers who got a christmas card from QVC got an easypay voucher in it to use on any item.
My husband has a QVC account and orders about once or twice a year at the very most (usually a pressie for me ) and he never gets incentives either so it must just be random
We also got a lot of sparkly things that fell out of the card all over the floor if I remember rightly. I wandered around picking them up - couldnt work out where the heck they had come from till I came on here!
