I guess it depends on a couple of factors:
1. The exchange rate.
2. The time of season. I’ve seen plenty of resort shops have mid or late season sales to clear stock - I once saved myself around Eur200 on a brand new pair in Ischgl in early Feb.
3. What’s available and whether you have a particular ski in mind.
4. The language barrier! When buying skis you need to be clear (and honest) about ability, style, height and weight etc and the type of skiing you want to do (also affects binding settings) - the sort of thing that can get lost in translation!
My advice would be to do your research before you go, pick your ski (or a range) and see if the resort shops have them. Even then, you won’t really know untill you try, so maybe get a pair on hire before comitting to a purchase.
Good luck!
