There is always just one fit; it just seems that there are multiple
fits - when you define your individual cases sloppily.
Well, this is an assumption to get a completely disjointed classification,
but this is not my case.
I have a first level discount if you pay online and a second level discount
if you pay online AND buy a special product.
So, the second is true only if the first is.

I don't see why "XXXXX" shouldn't come from a parameter fact.
As a general strategy, I try to avoid the "on-the-fly" objects
available with "from" and prefer these subordinate items to be
properly inserted facts. Usually this simplifies writing rules.
If I simply put several carts and the whole items form them into memory, it
would create a mess of carts and items, won't it?
What will keep each item with its own cart?
