Part of the agreement seems to be that the manufacturer goes out of their way to make a worse version for TJ's. Honestly they should be taken to task for flooding the market with fake competition, but that applies to the majority of brands in these days of megaconsolidation.
I don't think that is the case. As I noted in a sibling comment, many of TJ's store brands are identical to the name brand.
Buy a tub of the French Village yogurt I mentioned, and also buy the same Nancy's yogurt at Whole Foods, and you won't find any difference between the two.
