Lol, fair enough... But if you're actually interested, I'll provide some examples to show you I'm not just bullshitting.
This is using canadian Amazon and canadian Digikey, since that's where I'm from. We will compare single unit prices, since getting into bulk deals complicates things quite a bit, and is not what most inventors/hobbyists will need.
Since OP was talking about humidity sensors, the only one I'm familar with is DHT11.
On Amazon.ca this comes up as $11.30 CAD. [1] On Digikey this is discontinued but comes up as $7.67.[2] Yet even the Grove branded BOARD is cheaper at $9.37. [3]
Anyways, maybe not the best example since it's ancient and discontinued, was just off the top of my head. Lets look at something more recent like the SHT31-D:
Amazon: $14.69 [4] Digikey: $12.82 [5]
Also you can buy the sensor without the board for like 9$ on digikey. The selection is just way larger.
Out of curiosity though, have you personally used chinese boards on Amazon that are cheaper and generally reliable? If so is there a brand I can search for?
I'm down for cheap reliable chinese stuff (that you don't have to buy for like $50 in packs of 5 - 10 to get a discount...) off Amazon, just haven't been able to find any at all.
