Ibuprofen

If you’re willing to purchase 1,000 ibuprofen pills, you’ll pay $5 less at Costco. The winner here is definitely Costco’s Kirkland Signature Ibuprofen.

Cold & Cough

If you have a runny nose, you should prepare yourself to pay a couple of bucks, as these products aren’t exactly cheap. In this case, if you buy from Costco, you’ll have to take three of the Kirkland pills in order to equal one of the Up&Up milligram wise, but it’s still cheaper. The winner here is Costco’s Kirkland Signature Mucus Relief Chest, 400 mg, where you’ll pay $10,99, but you get 400 tablets.
