Cooking Spray
Cooking spray is something that any functioning household kitchen would do good to have on hand. Especially for those who bake frequently. This falls firmly in the category of things that don’t go bad quickly and can be purchased far more affordably in bulk at Costco. That makes it well worth looking into and, coupled with other items on this list, might help justify the cost of a membership.
Spices
It doesn’t matter what level of chef or the size of the family, spices are essential for any kitchen. The variety of spices included in one’s cabinet may vary. That said, even looking at just the basics, buying spices in large quantities makes financial sense. Salt is not going to go out of style. Pepper won’t go to waste. So why buy small quantities of it when higher volumes can be purchased at a much better rate? Pretty much any spice will last a long time if properly stored and the savings can be significant.
