Question: what’s smoother than a Samsung Galaxy S5 and costs around an eighth of the price? Answer: the Motorola Moto E, currently going for £79 at Tesco Direct. And hey, why not knock off £10 with code TDX-TH6W, making your checkout price £69.
Can be unlocked (from Tesco Mobile) for a couple of quid on eBay.
