Costco school supplies are showing up to win Back-to-School 2021. Shop as soon as you can because many of these items have Instant Savings offers only through July 25. And you know how Costco can be — when it’s gone, it’s gone, even if that happens before July 25.

To prove how low Costco’s prices are on these items, I’m comparing them to Walmart’s prices for identical or near-identical items. Walmart traditionally has uber low prices on back-to-school supplies and the fact that Costco blows them out of the water in these categories makes Costco worth your time.
