OMG, I love Costco! I think you would be surprised at how many bargains you'd find there. Also, their Kirkland brand is really top quality. I was a coffee snob until a friend turned me on to their coffee....love it. Same friend, from China, turned me on to the green tea....delicious. Their meats are great quality, and I always buy my salmon there. Their bakery dept. is great. I buy a whole bag of lemons or limes, juice them all, freeze them in ice cube trays and have fresh juice whenever I need it. I buy my cat food there, paper towels, toilet paper. You can get an eye exam and glasses there, cheaper. As someone else mentioned, their pharmacy dept. is cheaper, and you don't even need to belong to use their pharmacy. Their frozen berries are a bargain for making smoothies. I could go on and on. Maybe you could find a friend who'd like to shop there who would share the cost of a membership with you. I don't think you'd regret it.
not_ally, I'm just me, too, and I didn't think it would be worth it for me to join, and on some things it's hard for one person to take advantage. But with most things, like the salmon, I portion it out and freeze it. I have shelves in the basement where I keep the paper towels, cat food, etc. Having a Costco just 10 minutes away makes me a happy girl! Oh, and I forgot the garbage bags.....I only buy garbage bags once a year! LOL
