As a single person, I try not to overbuy too many goods, but I can't resist the call of Costco. I go about three times a year to stock up on my favorite staples.
Although many people venture to Costco for food, I mostly get household, health, and beauty products — like this Dove bar soap.
This package of 16 soaps sells for $16.99, which breaks down to just over $1 per bar. In other stores, a two-pack of this product can cost over $4.
