Best: Pills
If your insurance isn’t covering you for medicine and other pills, consider Costco. They are able to provide both prescription medicine and over-the-counter tablets. They do this at an affordable price, too. According to a study conducted by Consumer Reports, Costco was at the top of the list when it came to price. The research looked at 150 pharmacies in the U.S. before they arrived at this conclusion too.
Worst: Sunscreen
Did you know that typical sunscreens only remain effective for three years? So before you buy in bulk from Costco, you should probably look at the expiration dates on the bottles. If you think you will use all the lotion before their expiry date, feel free to buy. However, if not; you would literally be better off buying less for more elsewhere, you’d get better value for money!
