There's a paragraph for this

Concerning the Codemasters SoM "promotion".
Not only we are not getting any offer comparable to the one US gets.
Their offer is: if player has any multi-month plan by October 31, his accounts gets upgraded with Siege of Mirkwood FREE, while the regular price is 19.99$; not available to Lifetimers tho.
Lifetimers get SoM for free if they buy Adventurer’s Pack.
In other words, if you're a Lifetimer of have any multi-month plan, you pay just 19,99$

Now, offers for Europeans don't include this promotion at all. We always have to buy both.
That's sad, as we always seem to pay more for less, but that's not the funniest part. Math is.

Standalone expansion costs £14.99/€19.99
Adventurer's pack goes for £4.99/€6.99

Special edition however - expansion plus pack - was priced as £19.99/€27.99, while the only difference between it and buying the two products separately is a new, unique mount (another goat)

£14.99+£4.99=£19.98 (notice the extra penny missing)
€19.99+€6.99=€26.98 (notice the extra ONE EURO and a cent missing)

Neither of the offers makes the darnn goat FREE, as advertised on Codemaster's site.
But while I can live with one penny (still unethical), everyone paying in Euros falls a victim to unethical, misleading commercial practices because they do, in fact, pay for the FREE goat the ammount of 1.01€

There's a paragraph for that.
