Costco shopping & saving hacks
Sign up for the newsletter: Most stores, including Costco, offer a 10-15% discount just for subscribing to their email list.
Check the clearance section: You can often stack promo codes on top of already marked-down items in the sale or clearance sections.
Abandon your cart: Add items to your cart, go to checkout, and leave. Sometimes Costco will email you a unique promo code to complete your purchase.
Student/Military discounts: Verify your status with ID.me or StudentBeans to get a recurring flat discount sitewide.
