I fill scripts at Costco and buy "some" other items
from time to time, but I truly hate to give them my business.
I've driven by a number of Costco stores, but I have never set foot in one.
I typically shop at Wal-Mart for items such as toiletry items, household cleaning items, paper towels, toilet paper, soda pop, and hearing aid batteries. Each of these items I can buy in bulk and still save money. I could never buy in bulk and save money at the local grocery store.
