Just bought bunch of humidity meters from AliExpress. At 1/3 of Amazon price. I don’t care they will be delivered on day in February. Amazon’s price was just ridiculous.
I started doing this for my components and won't be going back to Amazon. I switched after getting some counterfeit components, and others so poorly soldered they didn't work.
It will be more expensive than AliExpress, but much less than Amazon and you'll actually get what you order...
You might want to check your DNS settings. I think they may have been hijacked.
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.

When I spent 2x as much from a US vendor from Amazon, they worked. No messing around. Probably they are built in the same regions, but US designs by US vendors I've had much much better luck with.
I don't buy lots of things from Amazon for fear of fakes. When you're on niche products that nobody cares to duplicate it's much safer.
It's almost comical the supply chain understanding you have to have to make sure you get the right thing.
