I have normally purchased my components from eBay -- including NodeMCU and sensors -- but out of curiosity I checked out AliExpress the other day. Conclusion? Similar or even lower prices, including on my favorite environmental sensor (the BME280). But when I just searched generically for 'pressure sensors' I got some hits like the one above. The part mentions *both* BMP280 (rare) and BME280 -- but at 1/3rd the cost of a typical BME280. It may just be that the sellers are unaware of what they are selling, or what is going on here?
