OK so not sure how to post this up as £34 or £40 because you do in fact need to spend £40 to get the deal but here goes.
If you do an online grocery shop of £50 or over (on your first order) you are getting £10 off with code F35FS10PM. You can add FIFA 17 to your basket as long as you choose the 29th (the day it comes out) as your delivery or collection date. FIFA is £44 in ASDA so if you add that to your basket along with £6 of groceries (may I suggest a copious amount of munchies to bunker in for a weekend on FIFA goodness) and you'll get the £10 off making the game £34 but ultimately your spending £40. I see it's £37 on Amazon the now so it's really up to people whether they want to spend the extra to get food and make it a deal.
