Where I’m at, a Costco membership pays for itself in 2 months with the savings on gasoline alone. Costco gas is nearly a full dollar cheaper per gallon than any other gas station around.
Also, try shopping in Costco without a cart. You’ll only be able to carry 2-3 things and it helps stop me from overbuying a bunch of stuff.
Costco is a religion and I’m all for it.
