Chip shortage made things tough but they’re still cheap when you can find one
How?
The licensed reseller that is linked on their homepage has prices starting at 43 dollars: https://www.cytron.io/c-raspberry-pi-4
Here in Latvia new Pi boards go for around 80-120 euros from what i can tell: https://www.salidzini.lv/cena?q=raspberry+pi+model+b&offset=... (this is a comparison site, on a page where actual Pi board start, not accessories)
Seems like you got a pretty sweet deal, if it would cost me around 16 times more.
