Discount warehouse chain Costco sells some things you may not be aware of, but may be considerably cheaper than elsewhere. Case in point; hearing aids and coffins.
If you are of hearing, you probably don't make it widely known - and most people don't even want to think about things like caskets. Both these things can be quite expensive though, and according to the Motley Fool, you should be able to save some money on both.
Most Costco stores have a hearing aid center staffed with licensed experts. In the case of this department, the chain sells the same technology as the heavily advertised name brands at about half the price. This might actually be the product line in the warehouse club that offers the biggest savings over buying from a traditional seller.
