From memory, there have been two price increases since October 2021 till now. Yes, some products have gone up 50%. There is a severe parts shortage, and everyone is competing for that limited supply - the highest bidder wins. Also, shipping costs have gone up incredibly (nearly 10x in some cases).
The bigger problem is not the price, but actually getting the kit. For example, right now, the lead times on some common items (for New Zealand) is:
MX68, 250 days
MS120-24P, 235 days
MV22X, 240 days
For my customers, I have had them forward order everything for the whole year in one go, so they can be confident of kit landing for projects starting later in the year. We are now reaching the point that if customers don't order their kit ASAP - they may not get it this year.
I would say if you delay ordering just 7 more days, you may not get some items this year now. It is that close.
