ColaPhotoCorbets in Ontario will mount them for free and within the day if its a slow day! I think we charge about 50 Canadian to get them mounted but a lot of the time we dont charge people because they bring in big business by buying new stuff every season. Happy costumer happy boss's. All workers get free mounts so thats a bonus :) - just buy bindings at the store.. free mounts :)
Most shops are all for taking care of their customers. Labor is the easiest to discount and its a great way to stoke out your people. Its the folks that buy all their gear online then turn around and want deals on labor that will put you out of business. Remember people, you get what you pay for.
