Not certain I would return a helmet asking for a refund if I crashed (and I have crashed, it saved my life... end of story), but you might consider purchasing a helmet through Performance Bicycles. I believe they take back everything, no questions asked. They are sort the Costco of bike stores. I have friends that buy products through both with the understanding they will forever return it and get upgrades for the one purchase price. Not certain if that is ethical but their justification, the store allows it so it must be OK.
