Discount problems

I'm a premium member and already have FM 17 on steam, I received a promo e-mail that therefore I should receive FM 18 from this site for £23.04, not sure how I get this discount as when I try to pay it says it costs £30.25.

Any help?

Sorry I should have posted an announcement in here (we did post on social media).

Unfortunately SEGA (via our partners) asked us to remove the discount as it's exclusive to the Steam store itself. Obviously this is really frustrating but unfortunately there's nothing we can do, we've got pretty much zero leverage to push for it what with just being a fansite.

Ok no problem thanks for the reply. Appreciate the effort of trying to get the discount and I would of easily bought it if it went through. Fuck the Mayweathers.
