Don’t Buy – Sunscreen
Sunscreen is one of those essential products for anyone looking to avoid a nasty sunburn when at the beach or even out and about on a daily basis. There is a time limit to the substance’s effectiveness, however, and most products will lose their protection after 3 years. At Costco, you can get a large amount of sunscreen, but you should check whether the stuff is nearing its expiry date as it could have been sitting there for a while.
