I did the math for my household and Costco is totally worth it for us

Just from the grocery bill alone, doing the math it is on average 30% cheaper just to buy there rather than our local grocery store and on top of that the 2% cash back from the premium membership and the 2% cash back from the Costco credit card works out to ~170$ net once you deduct the cost of the membership from it. We’re going to be putting all of these savings straight into our Roth 401ks!!! I’m so happy 😁 I just found this sub

Also their gas is 30 cents cheaper and the total cash back on that is 6%!
