Do DXO offer a discount after the end of the trial of pro raw?
Welcome to the forum @greatwhite
Except for Black Friday and YE discounts, DxO keeps the lid on pricing related variations. You could search the forum though and see if you can compile a pattern.
One thing: Chances of getting discounts seem to increase, if you subscribe to DxO’s mailings.
Other than that, I recommend to trial DxO PhotoLab instead and get the Elite Edition if you’re satisfied. PureRAW contains a subset of PhotoLab’s functionality. PureRAW’s functionality is almost un- tunable too, output options are limited, but the price is lower than DPL’s - but you risk paying twice because DxO offer no crossgrade discounts.
