No, you're right.  Don't like the object abstraction though.  I think
I'd opt for something along the lines of an object for the basket and
then objects with the items.  As for the multibuy discount, not sure

Seems like something that could reasonably be subtracted at the end of
the transaction though.

I'd guess there should be a checkout function in Basket to total
things up, which is likely where the code for discounts should go.

That said, my attempt could be random, but something like that... :)
