I followed Pixel prices for the last year, and rock-bottom for a 256gb version (the current absolute minimum for a device without an sd, to my eyes) meant 450€.
There are occasional good deals for (unused) older models on eBay, but they're surprisingly rare.
I wonder if Google demands stores to give the old models back, after the release of newer ones; they disappear from every store extremely quickly.
Interesting, here you can still buy the P10 and P10P for hundreds of Euros off and the prices are still trending down. Also many stores still have them. This is not surprising, because Google still sells them themselves, just in fewer colors and storage tiers.
