I can see that all offers goes in $.
I wonder if you should make an area option in your program (USA - Europa) (maybe because of language German - France)
and then make deals with vendors in those areas and make those links available when the user choose their place.
Amazon has many options for free p&p in their own areas, so if one shall import from USA the whole time..the p&p might be an issue to drop your offer and you loose a sale.-Rhutobello
The whole concept is not yet in place, so here is how it'll be when it's finished:
the program will be available in several languages. There will be a different version of the encyclopedia for each language. If you use the french encyclopedia, movies are shown with their french title, plot is in French, etc... Of course you can switch language, and all your personal data is still superimposed on the encyclopedia.
Suppose you use Coollector with French language. Then the price search displays only prices from stores with a french website (mostly France and Benelux), and currency will be Euro.
Now suppose you use Coollector with English language. In this case, you'll have the choice between 4 price localities:
1) american stores (with US dollar currency)
2) canadian stores (with canadian dollar currency)
2) australian stores (with australian dollar currency)
2) UK stores (with pound currency)
(of course you can swith between localities)
