, tasty muffins from its bakery, and even self-checkout kiosks (though there may be item limits). What it does not offer? Shopping to just anyone. You see, Costco is a membership-based warehouse chain, meaning if you want the perks, you have to pay the membership fee. It has started getting a lot more stringent about people sharing their membership cards with friends and family, but there is one legit way that you can add someone to your account: assigning your free household card to someone else who shares your address.

If you have a child (over the age of 16), parent, sibling, spouse, etc., who would like the privileges of shopping at Costco, as long as they live at the same address as you (and can prove it with an ID or driver's license, or a bill with their name on it — they might be asked), you can add them as your free household card holder, and you can do it online. Go to the Account Details section after signing into Costco.com, follow the prompts, and then head to the store to pick up the card. Or, you can have an employee add them at the membership counter in-store.
