Firstly, apologies for another Xbox 360 thread but thought it might be worth a mention for those still looking for a deal.
Looks like the 250GB version is back in stock at Tesco Direct and haven't seen this way of getting it cheaper posted before - apologies if it has.
Anyway, you MUST use code TDX-MAT4 to get an extra £5 off the price bringing it down to £154.20 (can't find a way of getting it cheaper anywhere). Code is entered at the final stage (click 'use coupons/vouchers' and enter the code ).
If you order before Midday today you also get Free Next Day Delivery.
Also, 318 Clubcard Points worth £3.18 in your next statement.
Possible Quidco/Topcashback as well.
Code can also be used to get the 4GB version with Harry Potter game for £119.
