I bought a Lego -set from Zavvi at Christmas. They were not the cheapest retailer for my product HOWEVER their promise of a 6% cashback via Quidco did make the difference and consequently I bought the item from them. No problems with the item - but then can anyone go wrong with Lego?
However the cashback did not track so I chased it up. Over 2 months later I am informed , on some unintelligible technicality, that Zavvi have declined the deal. They are very difficult to contact about this decision and as a result I wont be using them again.
