@Hawaii_Jake: I’m a Costco expert. I love Costco!
I have the Executive membership which is the $120 one. For 2019 I got back almost $500. I get tires, optical, pharmaceuticals, clothes, you name it. I have the Costco Visa which is my primary credit card.
Many people don’t realize that most of what’s on Costco.com you don’t have to be a member to purchase. Just a heads up, much of what’s on Costco.com is a little more than it is in the warehouse, and shipping is usually free. Some things are only sold in the warehouse, and some things are only sold on Costco.com.
When you order on Costco.com, there’s a tally that will tell you “you’ve earned ______cash back with this purchase.”
