I checked our mailbox recently, and to my surprise, there was a rebate check from Costco! I didn’t even realize it had been so long since I asked readers What Am I Supposed to Buy at Costco? 
After a year of shopping at Costco, it’s practically our main stop for groceries, gas, and various other things. We happily drove over to Costco and spent our rebate check stocking up on diapers for the babies !
Costco Financial Incentives
I found that the best way to make Costco worth our while is to stack the financial incentives. Here are my favorites:
- Executive Membership. This is what earned us our $75 rebate check. You get 2% back on all your purchases. No, don’t worry, we didn’t spend that much in groceries, a large portion of it was due to the new bunk beds the kids got for Christmas.
- Credit Card Rebates. We use the TrueEarnings® Card from Costco and American Express  to earn cash back.
- Coupon Book. Each month, we check the Costco coupon book for our favorites. It’s a nice bonus!
- Banking Deals. Costco offers other financial deals too. One that I like is the ShareBuilder $70 – $90 Sign Up Bonus . They offer a $90 sign up bonus for executive members and a $70 sign up bonus for gold star and business members.
We’ll be renewing our Costco membership shortly. When warehouse shopping, there are lots of ways to save buying in bulk , but you have to be careful not to get carried away.
