The list of DSiWare games (DSiWare->Games->Out Now) is a feature which I frequently use at nintendolife. I like the fact that you are able to sort the list by for example the rating. It lacks however one important thing: ability to sort the list by PRICE!
I might for example have 200 nintendo points left and would like to find something to buy. Now I have to check item by item how much it costs... And as new DSiWare is released every week the task gets more and more time taking..
And I suppose it's the same thing with WiiWare (I'm not owner of Wii yet).

That's an issue we've been discussing internally with regards to WiiWare; the issue is that price can differ between territories so some coding is required, but it's definitely in the cards!

Oh, I didn't know that. I'm not aware of any DSiWare game that has different price in different territories - are you? But if that's the case with WiiWare, I quess it can apply to DSiWare in the future as well.

Since most (>99% ???) of the software have same price tag in every territory, I suppose you could just decide to use USA price for example and simply add an asterisk or similar after the price to notify that the price may vary between territories when that is the case.

The solution will probably be along the lines of what you described: US price an then EU price where appropriate. Definitely on the list of things to do!
