For a small household, no, Costco not worth it at least where I live. 1) Pay to shop there 2) limited choices in personal care products, grocery staples, etc 3) proprietary packaging makes comparison shopping very difficult, eg. paper towels 4) parking lot is like NASCAR-bump ‘em cars hybrid 5) long lines 6) can buy, eg., large package of Bounty paper towels at Target where I shop for free, with larger selection of most everything. 7) Amazon has the largest selections of all, reviews (which I evaluate), free shipping and 5 or 6% cash back with Prime and Prime Visa, and zero time and gas wasted driving around.
