Right before you have a go for it being a Tesco voucher offer here me out. Since Gamestop ran out of magma red controllers many months ago, I had been looking around endlessly for a good deal to get a coloured controller. Then it dawned to me that i could cheat the tesco system by creating what is probably my 4th account to take advantage of year another code.
Added the magma red controller + a favourite of mine (Kylie singe and dance for wii for £2) and used the voucher (TDX-KYNK) for £10 off £50 spend.
If anyone can find anything else useful to add to the ps4 controller to bring it to £50 so that the voucher can be used, please post. I may use the kylie wii game for parties (probably for a good 2 minutes) but was not something i wanted to buy, and bought the total to a massive £41. But for the ps4 controller worth it.
