I understand that this is the regular upgrade price, which is reduced by 15 percent by entering the code given in the banner. I think that's right, because on a german dealer's site you get the upgrade for 149,50 EUR.
EDIT: Just I got the e-mail too. Interesting detail: In the mail the sale ends on 2022-12-15, in the top banner of the forum on 2022-12-21. I hope someone from MDA can explain this.
