There's a TikTok'er who posts shopping advice videos, and his "Costco tips" have been getting tons of hits. Here are a few . . .
In this one he shows you how to get the best value. The price tag sticker on the rack shows the "cost per use." For example, you could buy a box of garbage bags that are nine cents per bag, or choose the ones that are 21 cents per bag.
Here's another price tag tip. If it has an asterisk, that means the product will no longer be carried. If the tag is green, the product is organic. He also shows you how to spot the difference between full price, and a "manager special."
Also, if you're NOT a member, well, here's his advice on how you can get around that, and still shop there.
