Costco seems to be mostly full of old people and families . Singleyoung people generally don ' t have enough room in their homes nor enough need to make a membership worthwhile . I have always been on my parents ' membership , but only in the last 2 years have my SO and I had enough space to accommodate Costcosized purchases . Now we are saving on all kinds of items . We still stick to mostly to durable items like paper towels and frozen foods , or things we will use before they go bad , like their parmesan cheese . The key is to not let the samples sway you into buying something you wouldn ' t normally buy . <| sep |> I agree ! I stopped really having to think about it after the first month . Eating is so easy now .
