Louvers and vents look really nice.
I might have mentioned on one of your other threads, but i have a side biz with a friend making handguards for mountain bikes
www.geohandguards.com . We sell them on our website and amazon. Approx 80% of our sales are amazon. They are great to work with and their fees are reasonable, at least for small items with decent value. We pay $15 on our $75 product and $19 on our $95. The fees include listing, shipping, returns and storage. People seem to trust amazon more than a small companies website. Its a bit of work to set up your store and brand (its really designed to import good made in China.) We send them bulk inventory in heat sealed packages, then they distribute. They call it Amazon FBA (Fulfillment by Amazon) Amazon "sponsored" ads are really cheap too - a few $0.01 per click.
The best part is that we can focus on our products rather than dealing with shipping, customers etc
