Different Business Policy

In case you have seen our store in different sites: etsy, facebook, ebay and blogspot etc. , we would like to make one thing clear about the inconsistensy of the prices or shipping etc. Since there are different policy in different website, for example, bidding in ebay, we are not able to make the price/shipping exactly the same but they would be very similar in the same item at least. Ultimately we would like to make everything "buy it now" and make everything consistent in all sites- we are working on it!
