Medicine
While Costco may be a couple dollars cheaper and give you a few extra tablets, you may be better sticking with your local pharmacy when it comes to buying over-the-counter medicines and allergy relief. As with any product, medicine does come with an expiration date and buying cures for the common cold in bulk will only lead to more pills going down the drain. For quick symptom relief, it’s best to shop at places like CVS and Walgreens rather than increasing your headache trying to wander down the aisles of Costco in search of Advil.
