I saw your post on RFD; you sure can ask the Calgary Store to mount the rims for you. The staff I've dealt with in the Calgary store are very friendly and do their best to accommodate customers. Oh, and due to the extreme cold snap, energy consumption will be much higher so do charge as much as possible before embarking long journeys. Welcome to the club.
They are friendly, but I ask two salespeople and the delivery specialist and they all said the same thing. Maybe they can throw me a bone when I go to pick up tomorrow if I nudge them a bit.
