I don't think this is Amazon trying to trick anyone. Even though it's the same brand, it's two different sellers. The sellers make the listings, not Amazon.

The reason one shows the price breakdown in ounces and the other doesn't was because it wasn't set up in the listing to show that.

The shipping time is different because each listing has their stock in different warehouses.

My biggest gripe with Amazon is the third-party sellers all selling the same item they're importing from a Chinese company but rebranding it (poorly). As an example search for gaming headsets and you start to notice that the headsets being sold under different brand names look exactly the same. If you look even closer at the images you will see they don't even remove the original brand name from the headsets themselves.

To me the biggest erode in trust when I search for something and every result is the same item but rebranded and they're all at different prices with their own collection of reviews.

I've bought many items on Amazon trying to find the superior version to find out they're the exact same thing but rebranded.
