Buy: Kirkland vodka
It is a good idea to get any type of alcohol from Costco, but vodka has the best deals. The house-brand vodka at the warehouse is so good that some suspect that it might just be Grey Goose on the down-low. There are also sites that named Kirkland French vodka the best of the lot after doing a taste test.
Skip: Hearing aids
Hearing aids can get pretty expensive, and your insurance might not cover it. If you need them, you might know that Costco offers them for low prices. While you can save some money, you should think twice before getting a hearing aid from there. People said that there is poor service in some branches. On top of that, many locations do not have the right equipment to adjust the hearing aid as needed. If you ask us, you would be better off spending your money on hearing aids that actually work.
