I cancel my order for black version single sim from Tesco, here I will receive dual sim phone and £3 cheaper (even paid £4.95 for DPD home delivery).
Use trial WHICH for a £1 and get £20 off £150.
Quidco 2% off.
If you prefer the black version single sim, the price is the same.
OP To make you aware, next day delivery is £9.95 and uses DX Secure. They will not allow collection from a depot or deliver to a neighbour as they require a signature from the actual address. They also do not give timeslots (only 8am-6pm), and if you are like me and work weekdays, it was a nightmare.
