re: Does anyone get Gas at Costco?

In B'ham, it's about .15 cheaper than most places near the CostCo store. If you fill up once a week on a 15-gallon vehicle, you'll save $2.25 each week and thus about $100 a year on gas. As someone said already, that pretty much just pays for your yearly CostCo membership and unless you are meticulous in your financial documentation, you'll never really notice that you're saving money.

Though I do know someone who is pretty much OCD when it comes to keeping up with his money. He lives on a strict budget so much so that I wonder if he's thinking about it every hour of the day. But as he explained to me once on a long car ride, he's saving a little over $1500 a year compared to a few years ago when he didn't care about saving a dollar here or there.
