How I got an email from Costco’s CEO on a Sunday

I live in a city in the San Francisco Bay Area with a population of about 30,567 people (per 2010 census). We have a Safeway, Lucky’s, 99 Ranch, and most importantly a Costco. I like Costco. I only need to buy paper towels and toiler paper twice a year, get good prices of bourbon, and a 2-pack of Cheerios. Most frequently though, I shop at Costco for groceries – fruits and vegetables in particular.
