Just ordered this - seems like a good price if your after another one like me. In stock at Tesco Direct at the mo. for £24.97 add the attached voucher code and this brings the price down to £19.97. Add the sim for £2.47 to get free delivery - great tip from hotscot - select premium delivery so that you can choose a 2 hour slot. You can return the sim instore for a refund. So ends up £19.97 delivered, plus triple clubcard points come in at 81 (£3.24 in deals!) and don't forget to go through Quidco for another 3%.
For some reason it's not letting me attach Bookie's voucher, so the code you need is TDX-CLHD £5 off a £20 spend.
