O.K. prepare for a long post because I LOVE Costco!! Where we live Sam's is closer but we joined Costco, which is about a 20 minute drive. DH's parents have had a membership there for years and we used to go with them until we got our own. My parents used to have Sam's (no Costco in their town) so I can compare those two and the Costco is much cleaner, brighter, better quality grocery items, better store brand items, and nicer employees. I think the comparison: Costco is to Target what Sam's is to Wal-Mart is right. We get Costco coupons in the mail and they're on stuff we actually use so that's a big help.
We get all of our meat at Costco. When we get it home I repackage it into serving sizes (I weigh the ground beef) and freeze it. I like their whole chickens at .79/lb. Sometimes they have BOGO coupons so that's 4 chickens for like .39/lb. I also get their chop meat but sometimes I just get the pre-made frozen burger patties and they're really tasty and a good value.
We get the Basmati rice (it's in bulk so you have to repackage into baggies) and it's really good rice at a great price. We rarely buy bottled water but the Costco water is about $4/case. Their celebration cakes are yummy - HUGE - but very yummy and about $16! We also get a lot of our produce there and it's very tasty and lasts a long time. It's just me and DH so we have to get stuff we can freeze and store for a long time. I've never had a problem with things going bad.
We have switched to Kirkland (Costco brand) toilet paper, paper towels, and napkins. The Kirkland TP is exactly the same as Angel Soft but DH did a cost per square comparison (yes, he really did!) and the Kirkland is a lot cheaper. The Kirkland paper towels are large and very absorbant. I had been getting the Target brand paper towels and napkins but found the Kirkland ones work out to be cheaper and they're much better quality. I do not like the Kirkland tissues though, luckily they carry Kleenex at a cheaper price than Target.
I get Clorox cleaning items and Swiffer too. The Kirkland dishwasher powder works just as well as Cascade and is a much better value. They also carry Woolite and Clorox2 at a great price.
I get my contacts at Costco and can get 2 boxes of contacts for less than the cost of 1 box at my eye doctor. We develop our pictures there too. I think it's 13 cents a print. The quality is excellent and they're ready in an hour - enlargements too.
We have the "gold" membership, or whatever it's called, for $100 (regular membership is, I think, $50) because you get Costco cash back at the end of your membership year based on a percentage of what you've spent. If you don't spend enough to get at least $50 back, Costco will give you $50 - you can't beat that!
Other items we've bought: Michellin tires (including lifetime rotation and hazzard replacement for $20/tire less than Tire Kingdom); a hand-truck; a DVD player; designer jeans and tops. I'm sure there's more that I'm forgetting. Whenever we want a "big ticket" item DH compares Costco to other places, including the Internet, and gets the best deal, which is not always Costco, but it pays to check. Oh, we got my nephew a Wii game for his birthday - retail $24 and Costco $10!
We got our Corian countertops through Costco and saved 20% over any other retailer. Even the Corian discount people in our town said it was a great deal. We will get our master bedroom carpet through them next year.
Yes, you will walk out of there with a $150-$250 bill but, for us at least, what we by will last for months. DH and I track every penny in Quicken and we are very careful with our budget and we have found that we're saving on our grocery budget in the long run.
They take cash, check, debit, or Am/Ex. I just use the debit card and have never had a problem. Also, IMO, the food court is pretty decent. The price is right and the food tastes good. The other night DH and I got 2 hot dogs, a slice of pepperoni pizza, and 2 drinks (with free refills) and it was $5
No, I don't work for Costco, or know anyone personally who does, nor do I hold stock, although I wish I could!
