Yeah.. the long method name was to help clarify the meaning. ;-)

Again... it seems to me that these objects aren't allowed to
have methods, since that would require sub classing and according
to my understanding sub classing is sort of a 'deprecated' approach.

Maybe I'm missing something... I like your thought about the 'shop'
being the best object responsible for handling the shopping
baskets.. it's just a different way to slice the problem.. I could get
used to it. ;-)

thanks,
