Big difference with food, is that it's usually not quite as tasty. They cut corners to make it cheap. Whether that translates into some silly plastic thing Amazon is taking over production of, I don't know.

I always thought the store brands of things like that weren't independently developed, but just batches of the product it's cloning that didn't pass that company's standards or something like that.

Either case, they certainly don't taste the same in my experience.

Yeah, I doubt Amazon is cutting any corners. /s
