Summer sale season is here, and Amazon Prime Day kicks off on June 23 this year. But Amazon won't be the only place to find strong deals: We're expecting the return of Costco's Member Savings Days event around the same time, along with all of the wholesale retailer's regular price slashes.

Costco is a membership-based wholesale retailer. While non-members can shop with a guest account online, only members can access the full savings for the store's sales events (non-members can expect a 5% markup on purchases, and some deals are members-only). Memberships start at $65 a year (and you can sometimes find membership deals).

I'm a big Costco shopper and card-carrying Executive Member. And as a commerce editor, I'm here to help you sort through the sales and find the best deals possible. Here are my favorite Costco deals to compete with Amazon right now.
