It would be a good idea to sell this as a download, this will be a very popular dvd and allot of people will want to have it and if a person who lives in europe is going to order this the shipping is very expensive and if it gets into customs the shipping price usually costs two times more then the actuall product so a single effect dvd ends up costing like 100 - 120 dollars.
I dont do it, but i know allot of magicians outside the US that really wants to buy the effects from the dealers, but they cant afford to pay the expensive shipping, taxes and other stuff you need to pay to get it into your country so in the end the dvd costs 120 dollars, so they do download it illegaly from different sites or gets it from friends that has it in the US.
