## What its pages say

Quoted word for word from costco.ca's own pages.

- In their own words: “In less than two decades, Costco has transformed the retail world. The Costco story begins in 1976, when entrepreneur Sol Price introduced a groundbreaking retail concept in San Diego, California. Price Club was the world’s first membership warehouse club, a place where efficient buying and operating practices gave members access to unmatched savings.” (https://www.costco.ca/about-us.html)
