As a reference ... we've been selling Oneway products on Ebay for a while.
You can check out our current listings (and feedback) on my Ebay store at
http://stores.ebay.com/Going-Bunkers. Oneway has told us our Ebay prices are
too low (they have asked us to sign a MAP policy) so we will soon have to
stop our Ebay listings.
