Surprise! 12 Things You Probably Didn't Know You Could Buy at Costco

Costco (NASDAQ: COST) has built a growing following of loyal members partly because it offers low prices, but also because shoppers never know what they may find.

Every one of the warehouse club's locations carry certain staples, but they also have some goods and services you weren't expecting to see. A visit to Costco or even to can uncover surprises.

Yes, Costco is the place where you can buy bulk items at generally very good prices. It's also a place and digital destination where you can go treasure hunting, looking for new ways to make the $55 or $110 you spend on an annual membership even more valuable.

Perhaps not every item on this list will shock you, but many Costco customers are not fully aware of the depth and breadth of the warehouse club's offerings. Here are some of the best hidden, or at least semi-hidden, things you can buy at Costco.

1. Caskets (and funeral supplies)

While someone dying seems like an odd occasion for a trip to Costco, the company does sell caskets and the savings over buying one from a local funeral home can be considerable. The warehouse club also sells other funeral-related items including urns in case the deceased elects to be cremated and you need a place to store the ashes.
