Costco! I must admit, if you want something at Costco, you'll love it. They have that. In very large quantities.
If you want something that isn't (or only might be at CostCo) you might be out of luck. What's worse is if you want something you got once from CostCo. Like these great slippers I got that are now wearing down. They were delightful and warm and had a good grip and could even be worn outside.
But they don't have them anymore.
Sigh.
You can even get food after you're done shopping, and cruise the breadth of the store nibbling at the sample stations. Reminder: Tasty hot stuff goes fast.
Occasionally, what you're looking for will be on sale. I'm not going to lie to you, Marge, that's very exciting.
