#77 Picking Up Discounted Groceries
Even though I hate shopping at a certain big box store (rhymes with call dart), they have this grocery pickup where you order your groceries online, drive to the store at your appointment time, and they put the groceries in your car for you. The loophole is that for new customers if you use a coupon code, you get $10 off. Every single time I use this service, I create a new email address so that I can use that coupon code.
