8% through topcashback making it an unbelievable £22.77 delivered. (£24.74 without TCB)
I got it by using the following 2 codes at checkout - GAMES5OFF-1 (gives £5 off pre-order) as well as FTSL15-1 (gives 15% off). I've already used the FTSL code so again have used a different email account to get it to work. (Quoted from STOPHA)
If this upsets anyone then apologies, didn't see it advertised and surely must be worth a punt.
Looks like they wont take payment until the game is dispatched so nothing to lose if it comes up cheaper in the meantime.
