Worst: Sunscreen
Sunscreen will only last up to three years before losing its effectiveness. If you buy a multipack from Costco, be sure to check the expiration date and know that you’ll be able to use it up in time. Otherwise, you’re just throwing money away.

Worst: Disposable Razors
Despite the fact that it seems like buying a big box of disposable razors seems like a great deal, you can actually find better prices at Walmart than Costco. While Costco sells 14 Kirkland razors for $23 ($1.64 per razor), you can find 10 Gillette disposable razors at Walmart for $7.97 ($0.80 per razor). That’s almost half the price!
