Welcome to Costco! I love you.

Gas
And generally higher end stuff is relatively inexpensive. We found a washing machine for about $230 less than Home Despotism
We like the yellow-bag coffee too
If you find you are regularly buying stuff there, get their Citi credit card (and pay the balance monthly) as the points add up fast and you can more than pay for the membership

Best thing about Costco in our area is they deliver same day for less than the time and gas required for me to go there and shop. I’ll never “go” to Costco again.
Some things we buy a lot of:

All grocery staples
Coffee
Snack foods
Gift cards that offer discounts (airlines and attraction type stuff)
Flowers for the wife

They have a bag of 347 dinner rolls or two giant loaves of bread in the bread aisle. If you are feeding 43 kids its perfect.

Haven't had their frozen lasagna in a while but its awesome. Steaks and prime rib are spendy but very high quality. I bought a tenderloin last year and made Beef Wellington it was perfect.

Never know when you'll need a 10 pound box of Rice Crispy treats, but you will know where to buy one.

Not only do they support BLM and hate America as only a Seattle based company can, but they'll send you a magazine every month or so telling you about their latest Tampon Tim rally or pedophile outreach program. Their employees seem to enjoy working there.

Almost anything and everything.

From supplies like toilet paper and dish soap, to furniture, appliances, TVs, gun safes, sporting equipment, car batteries and tires, alcohol, meat, charcoal, etc.

If I'm in the market for any decent sized purchase, I always check Costco.com first. I'm eyeing a "mobile workbench" on there right now to turn into a reloading table.
 
Everything nonperishable is good to go. For groceries you better be raising a small tribe or have a vacuum sealer and lots of freezer space.
Great for large families. I see the sister-wives once in a while during the week at Costco. Usually 2 or 3 in prairie dresses and kids with a couple of the huge flat carts piled high. Just the right quantities of everything!
