Tim Hortons review: coffee prices

Despite questioning the amount difference in Kensington PEI Tim Hortons compared to Ontario Canada, I was charged 2$ for a medium coffee, when it is listed at 1.79$ for the medium coffee at Tim Hortons franchise.

As a franchise the prices should not change regardless of location, and I am very disappointed that this is the case. I am a Tim Hortons coffee drinker daily and as a shift worker I drink a lot of coffee. Please look into this and I hope to not be due her disappointed by Tim Hortons.
