Costco is awesome. I only go about once per month but it is so worth it! I love stocking up on paper goods and necessities - especially when they have a discounted rate. Some of my go-to items are toothpaste/mouthwash, marinated artichoke hearts, pole-caught tuna, bottled sauces, spices ($10 saffron?), frozen berries, cat litter, and anything else that is simply too good a price to pass up! They actually have very high quality clothing as well for a bargain. They used to carry my favorite leggings, however, they discontinued them recently. My only complaint is that they never let you know which items they will not be carrying in the future (I would like to stock up when I can!)
