I think we've covered Costco a few times on this board... but I'll take any opportunity I have to talk about how much I love Costco
I grew up in a BJ's warehouse family and when DH (then DBF) told me he was a Costco member I scoffed and said- well they're the same thing, right?
Wrong.
Our regular purchases:
$1.50 hot dog and a soda (even on Kauai in Hawaii!!)
Kirkland's toilet paper (unless Charmin is on sale)
crystal light lemonade and tea (great deal)
DH's acid reflux meds (omeprazole) - this pays for our yearly membership by itself
Fiber one bars
Babybel light laughing cow cheese (insane mark down from our grocery store)
Smart balance
stuffed salmon (I don't know if it's a deal but its GOOD)
pork tenderloin
secret clinical deoderant
razors
zicam
shampoo, conditioner, body wash, soft soap- almost all toiletries
Awesome deals:
$70 for a heated mattress pad (same one was $150 at BB&B)
$25 backpack beach chairs ($50 elsewhere)
$50 for a stainless steel trash can that used regular kitchen trash bags and came with a mini one for our bathroom- would have spent over $100 elsewhere
Beer & wine for our wedding - can't remember how much we saved but a lot!
We're just a couple with no kids so I'm sure once we have them we'll be buying more food items. Also would buy more meat if we had an extra freezer.
On our honeymoon we went to Kauai and Maui and visited costcos there. We bought some of their pre-made food to eat lunches out on our balcony at the resort. Also bought Kona beer there for cheap.
