Costco , 4 things to buy .

Here is an article I just read about what to and what not to buy at Costco.  4 Things to Buy at Costco

I personally have a Sam's club membership. It was a gift
from my mom. When I go I buy the same handful of
things, Rotisserie chicken, french bread and laughing cow
cheese. I haven't been to Costco. I imagine it is somewhat
the same.

Here are the 4 things mentioned to buy :

Chocolate truffles
Eyeglasses
Laptops
Extra virgin olive oil
