I have gone the with option 2. Basically I have two forms in the template.
Form 1 lets the user add an item. Form 2 keeps a running tally of the items
thus far added. What I can't figure out is how to make dancer differentiate
between the two forms so that it knows that the user is done adding items
and wants to check out so to speak he can hit the submit button of Form 2
to save all his submissions. Both forms have submit buttons but I am not
sure how to make the POST route understand that the user is done with the
form so that I can in turn make it save the data.

Thanks for any ideas.
