Chips, Please

I love avocados, and have gotten accustomed to the standard $1.50 price tag back home.  Here in Kenya, avocados are commonly grown, and sell for 10-30 cents apiece, depending on size. And size is in the eye of the beholder. My 7-inch "medium" is going to make a whole mess of guacamole. Now if I could just find me some tortilla chips .  .  .
