Bought snow tires at Kal tire North Hill store. However, their credit card authorizations machines did not work. I overheard the clerk tell the manager that they tried several times earlier in the morning and it didn't work before plus they reset the machines. I had left the vehicle about an hour earlier for installation. The manager told me to pay in Cash (Don't know about you but I don't lug around $1800) BLACKMAIL - WHY DIDN'T THEY TELL ME BEFORE I LEFT THE CAR AS THEY KNEW EARLIER.
