This is my first deal and first post, so please be gentle :p
I just ordered Halo 3 from Powerplay direct for £11.49 delivered! Next cheapest must be around £18, bargain!
There is a 2% voucher, which brings the price down to £11.26
Also dont forget Quido for 4%, to bring the price down to £10.80 (I forgot to use quidco :()
