There are certain brands I cannot sell on Amazon because their manufactures will claim I am not a certified reseller and thus am committing copyright infringement (Amazon says nothing about needing to be a 'certified reseller') and they threaten to have my entire store shut down. It's how they keep the prices of some things artificially high. So it's funny that they can't get real counterfeit things off their website.
