The Quidco / AliExpress relationship is excellent
Very speedy tracking, accurate cashback rates combined with keen pricing to start with mean AliExpress has become one of my favourite marketplaces. Never had an issue with cashback, paid out promptly and often at what seems like quite generous rates. As a marketplace delivery speeds and service with individual retailers varies but the rules and guidelines of the market make transactions seamless on the whole. I've had the odd item fail to turn up but when the price doesn't seem to even cover the postage I'm not surprised, refunded immediately without any of the hassle imposed by some of the other merchants operating out of China / Hong Kong, the difference could not be more stark.
