Dave Swanson and Samantha Matt of Reviewed.com put together a list of eight hidden benefits of a Costco membership.
One is Costco Online, which sells thousands of items not available in their warehouse stores. The more unusual items available include caskets, urns, telescopes, steam saunas, Fitbit wearables, chainsaws, and a 5.3-carat diamond wedding ring.
Another great Costco.com find? Year-round access to seasonal items.
