We are two adults and a toddler and like the membership, primarily because there are a lot of restaurant quality frozen items. We buy mostly food and do have storage space. One way you can offset the cost of regular membership is to get their Costco Amex which gives cash back on all purchases in the form of a once a year check that you spend at Costco. For us this means we get a free shopping trip a year and a free membership.

You don't have to join -- just go with a friend who is a member.

I think it's worth it. I buy seafood and meat in bulk, plus there are a few things that I like to get either myself or the kdis that Costco sells for way cheaper than getting it at the grocery store -- a particular brand of granola, juice boxes, cheese sticks and fruit snacks. I tend to go whenever we run out of those items, so maybe every 2-3 months?

I don't think their prices for organic milk are any better than at Wegmans.

Ack, posted too soon. We don't have room for bulk purchases.

We are two adults and a baby and just aid for Amazon prime now that Amazon mom ran out. It is so nice to have the free shipping!

worth it if you use their coupons and have room to store bulk items.
