Why does Harbor Freight have so many similar products with different model #'s

[SAWYER]

I am looking to buy a polisher and there are various models that look similar and I have noticed this with other stuff on their site before. The prices will be different on the different item numbers, what is the reasoning for this?

Off brand. Or those name brands dont wanna be associated with Harbor Freight.
Cant blame them.

I'm sure their stuff gets contracted out to the cheapest Chinese factory. Change factories, change model #s, adjust price.
