I'd get one from online but am really, really wary of the fit. My favorite online shop doesn't carry them and the others that do have a restock fee which I absolutely refuse to pay so that limits my options. IMO, since gear is so expensive to carry for local shops, the online retailers are ultimately going to be the real winners, but only those that provide the optimal customer experience of easy to swap sizes/models/brands without charging the customer out the rear.
Shoes are similar in nature and the major online retailers even provide the return shipping label!

I picked up my Shark lid today, sadly, having no knowledge of helmet fit, I walked away (and the guy who was helping me let me walk away) with a helmet too big for my head. So tomorrow I will have to do a little return shopping.
