Damage to my chrome tech wheel rims

Unfortunately, I ran up against a curb and the chrome tech wheel rims got scratched and kinda bruised in a spot. Does anyone know how much it would cost to buy one new wheel at the dealership or online? Do people normally replace a wheel when it gets damaged from the curb or does it happen so much that you just live with it? Can these things be repaired to look like new or is it just better to buy a new one? Thank you.
