I use to be a production manager at a pharmaceutical company and we would package over the counter medications for dozens of different companies but all the product was the same.
Instance, children’s liquid IBprofuin. The liquid was all from the exact same batch and we would bottle it in the same bottles and run 20,000 dozen for Walmart…change the labels on the machine and run 20,000 dozen for target. All the EXACT same but difference of 300% in price at the store.
I’m sketched out now on any products…like you stated, a lot of products are all made in the same facilities and labeled differently.
I wouldn’t be surprised if all the welders people are debating aren’t all built in the same factory lol
