Costco membership offers hidden savings beyond groceries: 5 perks to know

A Costco membership is best known for bulk groceries, the $1.50 hot dog combo and towering packs of paper goods, but some of the biggest savings can happen well beyond the winding checkout lines.

From travel and gas to gift cards, optical services and warranty coverage, Costco members can access a range of discounts and services, according to the company’s website and news reports.

Here are five lesser-known ways shoppers can stretch their Costco membership outside of the warehouse aisles.

Buying Costco gas can help households offset the annual membership free, according to Money Talks News. It often costs less than competitors, though the actual savings vary by location and driving habits, according to the outlet.

An additional perk is that Costco members can check local gas prices and station hours through the Costco app before heading to the pump.

And another secret at the pump is that the warehouse’s long hoses also allow drivers to fuel up from either side of their vehicle. "Whether your gas tank is on the left or right side of your car, you can choose the shortest line," Costco's website reads.
