Some of our favorite Costco products are things that seem eerily similar to nearly identical items made by other brands. There are always rumors that the store’s Kirkland products are actually sourced from name-brand manufacturers, but often, it’s hard to verify if those are facts or just rumors. But there are some Costco products made by other brands that have been confirmed, according to MoneyWise. Finding out which generic foods (for humans and pets) and kitchen products are actually made by big-name brands can be handy if you’re trying to comparison shop, finding the best prices while still getting the quality goods you’re used to.

Baby formula can be expensive, but no one wants to skimp on quality when deciding what to feed their little one. The perfect compromise? You can buy Kirkland’s Pro-Care Infant Formula, which is made by Perrigo.

4. Jelly Beans
