Gas prices are high, but a lot of people are swarming one local fill-up spot to save some money.

People are willing to wait in line at Costco just for a better deal.

The head of petroleum analysis at Gas Buddy, Patrick De Haan, explains that Costco is strategic in having lower prices.

"It's certainly a different price strategy. It really works out for them. Of course, if you go into their stores, that's where their profit margins are better. So for Costco, it's all the strategy of getting people into their stores."

Their gasoline profits may not be making them a fortune, but it's bringing them the sales inside.

"They're very aggressive. They want to get people in their stores, and that's how they do it. They are willing to accept less margin in exchange for people visiting their stores to stock up."
