Sandwich Bags
Well, seems like Costco owns the game so far because I’m about to recommend you go to Costco AGAIN if you’re looking for sandwich bags. Costco’s ziptop bag is Ziploc, so it doesn’t offer any Kirkland brand alternative. After comparing the prices you’ll find at Costco and Target, we concluded that Costco is a cheaper option but only by a penny.
Liquid Dish Soap
The Wirecutter gives a thumbs up to Kirkland’s product, even though the reviews weren’t very keen on the scent. But, it’s biodegradable, so I guess that’s a plus. As for the Up&Up liquid dish soap, its customers are very happy about it, but it costs more by 2 cents.
