Special personal trainers - is it worth the price?

[MNK Kaskada]

Interesting, you guys don't have the same offer, it seems. It's been up for a couple of days and ends tomorrow. The offer is to use special trainers to get my six star players to seven with reduced prices.

Other examples:
118 to 120, 14T
109 to 120, 91T
100 to 120, 176T

Maybe a regional thing? (I'm from Northern Europe) Or targeted to certain managers by some other criteria?

Did you have that special update or something. We dont have that. Give as some pictures, I need to understand that.
