I love Costco. I mean, I REALLY love Costco. I go at least once a week, sometimes more. Their roast chicken is to die for, and I love that you can buy everything there. While driving home tonight I was telling my husband about my love of Costco, as if he didn't already know, and how I think we could easily live off of only shopping at Costco. Which brings us to this challenge =) So today is Sept 29th, and I will need a little time to figure out the rules and such, but give me some feedback. What rules would you like followed? I have two kids, but I don't think that should really interfere with shopping at Costco only. Any particular rules you'd like to see followed?
