Right before I get destroyed hear me out. If you have got any vouchers lately from Tesco you will have seen that they are doing a price boost ie you get double for your money. So for instance I got £55.00 which equated to £110.00. Add in the code TDX-KYNK where you get a tenner off any orders over £50.00, it works out at £230.00 (at price of £350.00). I know that the price of standard ps4 dropping by a few quid in places so might be worth a gamble holding on for a few weeks to see if Tesco follow suit so it's even cheaper. The deal is dependent on the vouchers, so obviously the more you have the netter it will be!
