Kirkland Signature is the retailer's private label that offers "even better value" for members with items "at the lowest possible prices."
There are Kirkland versions of groceries and household essentials that dupe name brands like Nutella, Philadelphia, Häagen-Dazs, Bertolli, Ziploc, Tide, Advil and Tylenol.
Narcity checked prices at Costco, then compared the store brand to name brands, and found price differences up to $19!
