Jozef,
The official upgrade price is very steep.
If I recall correctly you get a discount of 31% of the official list price of the P30+ which is an amount around $4.5K.
Again if I recall correctly that still leaves $17K+ to be paid...
In December there was a promotion of around $15K for the upgrade.
A lot of money for a nice screen imho...
Best, Joris.
