With some products, it's really hard for manufacturers to make a "seconds" type of the same thing without ruining it.
I have a friend who used to work at a mixing-packaging company that made several of the more popular sauces here in the south. He said some of the products had as little difference as the addition of xanthan gum to the mix. Other than that, product X and Y were identical. X was a name brand and Y was a store brand.
He told me about many products that were that way. They made him sign a non-disclosure statement before he could work there. He gets all nervous when we discuss it.
