I was not even aware there was a Starbucks at Memorial and Edmonton Trail. I associate that corner with the Centex gas station that is almost always one of if not the highest priced in the city. As such, I never stop there.
EDIT: according to gasbuddy, most stations around downtown are 145.9¢/L to 148.9¢/L. That Centex? 14
9.9¢/L
