Buy: TVs
Costco is not the place to go if you already have a specific TV in mind. However, you can get a set that works just fine if you are a little more flexible. Not only can you get a TV for a good price, but you can also get an extended two-year warranty to go with it.
Buy: Golf balls
Are you thinking of getting some golf gear? You should get them at Costco next time! The warehouse actually has a golf ball under its Kirkland brand. Golfers seem pretty happy with the products. Golfalot tried out their balls and said that they are comparable to premium ones!
