Just curious how those that sell on their own website AND the marketplaces price their goods.
We sell just about the same on our website as we do on E-Bay. A few items cheaper on E-Bay and a few cheaper on our website depending upon E-Bay competition. Occasionally we have sales on our website that is NOT carried over to E-Bay (mainly because it's so difficult to implement)
On Amazon, it's another story. We charge almost full list on everything due to the excessive fees over there and the fact that they don't collect sales tax (9.75% over here!). But there a few nutjobs selling there that either don't know their math, or got stolen goods that sell below cost.
