Buy: Generic Drugs
You will probably use a number of these in the Costco warehouse before it expires if you take an over-the-counter medicine such as ibuprofen, Tagamet, or perhaps an allergy medication on a frequent basis. You’re going to pay a fraction of what these medicines will cost you, and you don’t frequently run out of generic drugs.
Don’t Buy: Personal Care Products
Don’t overdo it, even though the price is right, with those Costco care products purchased. “Personal care products often come in massive bottles or in multi-packs. I prefer multi-packs because the product inside stays fresh, but a general rule is that you should only buy personal care products that you go through quickly,” Bodge said. “Certain products, like face creams and sunscreen, may spoil or lose their efficacy over time.”
