Whether you’re already a member but never thought to look for these products at Costco or you don’t currently have a membership, comparing prices on drugstore essentials can seriously add up. The warehouse club store frequently offers larger versions of these products at much cheaper prices per unit.

Here’s a look at 10 products you can save money on by shopping at Costco.

Vitamin D

Most foods do not naturally contain vitamin D; so, if you’re like many people, you take a supplement to get your daily intake. However, there’s no need to pay more for your vitamins than necessary.

Walgreens sells a 90-count container of Nature Made Vitamin D3 2000 IU softgels for $12.99 — i.e., $0.14 per vitamin. Seriously more affordable, you can get a 600-count container of Kirkland Signature Extra Strength D3 2000 IU vitamins at Costco for $14.49, which equates to $0.02 per softgel.
