I wear Giro -- a few years ago I had a crash and needed a new helmet. Went to LBS and they immediately gave me a new helmet at $30 off when I returned the crashed helmet. They mailed the broken helmet back to Giro for me and gave me Giro's replacement warranty, so I go the discount and didn't need to mail anything myself. Not the $20 replacement talked about, but I still thought it was good and appreciated the return policy/discount.
