and their products are generally higher quality but also higher cost than many grocery items when the quality may not matter as much. There are things were quality matter and Costco is great for that. But unless you live in Hawaii like one poster, cancelling the Costco membership and shopping at the best priced grocery story will likely save you a lot more money and a lot more time. You still have to go to grocery store if you shop Costco, but you don't have to go to Costco if you shop at a grocery store. So add in the extra time and gas and expense to shop 2 places and Costco costs a lot more.
