You Should Definitely Be Buying These Things At Costco

9. Vitamins And Supplements
Costco carries a large number of vitamins. The retailer offers everything from multivitamins, to vitamin D, to all kinds of supplements. And, in true Costco fashion, they are great prices.

For example, the bottle of multivitamins pictured sells for $19.99 when you buy them online. The exact same bottle of vitamins sells for $24.47 on Walmart.com. Costco's other vitamins and supplements can be found at equally low prices, and the store typically has an extensive selection of all the latest, most popular supplements.
