Ordered 2 sets, 17" and 18" through TireRack instead of SimplyTire, saving about $700, after paying taxes at the border. Then $20 to install a set of wheels so savings down to $640. Gas - $50 (but can recover the bulk of this if you start driving with a half tank to States and fill it up in States). Then you pick up packages from the mailbox, buy groceries at Walmart and head back.
It's more like $20 per tire to install,mount and balance
