I went to Costco with a guy friend (FYI: I only "like" girls).
My friend doesn't have a Costco membership. He is a super smart computer programmer from Ukraine. He earned his masters degree in his early 20's, and is invited to The US to work at a dot come industry.
He loved Costco. He was keep saying "Exciting stuff", "Exciting stuff..." I think he will get a membership soon. He picked up a pair of windshield wipers. Rest of the items were for me.
Kirkland Signature's Lake Country Cheese is pretty good. I'm glad I took a gamble.
I bought Charmin bathroom tissues. I didn't buy Costco brand. :(
I stocked up on Spam. I love Spam. They will last 1-2 years, I think.
I bought 2 more T-Shirts. I am still trying to stop wearing cheap undershirts to work. It was OK to wear undershirts to my old job. But not any more.
Q-Tips will last me 5-6 years (if I keep living alone... )
Tire inflator (air compressor) was $39.99. It's been a hassle to go to gas stations to inflate tires. I often drive with soft tires for months until I find time to go to gas station for air.
What you don't see in below picture is a lobster tail.
