Do not expect any cash back from this supplier as it does not happen!!
Bought my husband some Ray Ban sunglasses through Quidco from Mister Spex, just over 2 months later my cash back has been declined saying I had returned the item.
I have not returned this pair of glasses only a second pair purchased after his birthday as he wasn't sure which ones he liked best!!
Delivery was good, price was average but if I had known cash back would be defined would have probably looked elsewhere!
Return for second pair of sunglasses was easy, although had to chase up the refund to my card.
