It's hard to find. Pixel 8 costs $670 here, and the cheapest Pixel is 9a for $470. At this price, it is overpriced. Pixel 8 has 8 GB RAM, Samsung A16 with 8 GB costs just $230. It's almost 3 times cheaper. And Samsung supports 2 SIM cards, unlike Pixel, so you can have, for example, one SIM for Internet and another for calls.
As mentioned, second-hand is also an option. But my price was actually from Hungary with world-record VAT included, so not sure if you really couldn't find/order it for around that price.
Also, the basic premise is that you can buy a decent Pixel phone for an affordable price, not that it has the very best price/value out of any device. I would also wager that the Pixel 8 has massively better cameras than a Samsung A16, so not apples to oranges.
Used or refurbished devices are typically much cheaper. It's what I would recommend.
You can also use 2 SIMs on a Pixel by using an eSIM.
