Acetum Balsamic Vinegar
Since partnerships can be profitable, Costco partners with a lot of companies. For instance, they signed a deal with the company Acetum Balsamic Vinegar, which now produces the really popular Kirkland Signature Aged Balsamic Vinegar of Modena. Amazon’s whole foods sells the Acetum version, but the same product is priced lower at Costco. The packaging is different, though. Nevertheless, what’s important is what’s inside, so getting the cheaper one makes more sense.

Perrigo Infant Formula
When choosing which baby formula to buy, it is essential to consider the quality. However, a lower price doesn’t always mean the formula is subpar. Abbott Laboratories, which is the same group behind Similac, made the Kirkland Signature ProCare. While the partnership between Costco and Abbott lasted for quite some time, it appears Perrigo is now working with Costco. This explains the new packaging. However, nutrition is virtually identical, with the new formula having a slightly higher carbohydrate content.
