I buy from Costco all the time. The regular purchases are toilet paper, paper towels, garbage bags, cat food, tissues, milk by the gallon, berries, bananas (3 lbs for 1.50), When people tell me they aren’t a member of Costco or Sam’s because they don’t eat that much, I tell them “you will eventually use 100 garbage bags.” I use Costco for other things, too, like clothes, appliances, garden stuff, holiday stuff, but I digress.
When the pandemic first started, I had just purchased a pack of toilet paper at Costco, and throughout the pandemic, I bought a few more so I never worried about running out, the way a lot of people did when there were toilet paper shortages. I also bought a 25 lb bag of Basmati rice and I had to buy a big plastic dog food container to hold the rice, and I bought a box of 25 plastic containers. I was concerned about food shortages and my ability to get out and get food, so I figured we could do rice and beans if we were desperate. I also buught a bulk purchase of powdered creamer, because I wasn’t sure if I would be able to get to a store to get milk. It turned out I could get out to stores on a regular basis, but I still have the rice in the container and I think I would do a bulk rice purchase again in the future.
