1. Not earning cash back
Hopefully you already know there are multiple ways to earn cash back when shopping online — including on wholesale clubs’ websites. But you’re leaving money on the table if you aren’t also earning cash back every time you shop at a Costco, Sam’s Club or BJ’s store.
A free app called Ibotta routinely offers cash rebates on purchases from these three chains’ brick-and-mortar stores — among many other retailers’ stores.
To start using Ibotta, sign up for an account, which is free. Then, download the app and launch it. From there, you can select Costco, Sam’s Club or BJ’s from the list of retailers to see what cash rebates Ibotta is currently offering for purchases from those wholesale clubs.
Of course, you can also always earn cash back by paying with a cash-back credit card.
