FM18 Preorder Discount Issue

I am looking to preorder FM2018 with Premium SortItOutSi mebership and with contract extension discount as outlined in promo emails but when I attempt to purchase the price is coming in at £35.65 rather than the £31.04 listed. My Steam account is added to my sortitoutsi profile and all set to public. Can anyone help?

Cheers!

Same with me I'm also a premium member who has FM 2017 on Steam and looking to get the discount for £23.04 as it says in one of the promo e-mails:

FM2018 Savings Comparison
FM18 + Premium Membership (normally £10) if you own FM17 £31.04 SAVING: £16.95
FM18 for Premium Members who own FM17 £23.04 SAVING: £14.95
FM18 for Normal Members who own FM17 £26.14 SAVING: £11.85
FM18 + Premium Membership (normally £10) £38.65 SAVING: £9.34
FM18 for Premium Members £30.65 SAVING: £7.34
FM18 for Normal Members £35.82 SAVING: £2.17

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.
