Costco members can take advantage of online savings on healthcare products. Purchasing five select pharmacy items qualifies for an automatic $30 discount at checkout. I spotted vitamins, earplugs, and probiotics and combined this offer with instant savings for a total 46% discount. While membership isn’t required for this deal, nonmembers will be charged a 5% fee at checkout.
