Generate Single Page From Multiple Nodes ?

Here's the situation:
I have a potential customer who has a website that aggregates various coupons for local businesses. As it stands now, her site is made of static pages that she updates by hand, and each coupon is an individual page that must be viewed and printed by itself. What she wants is the ability for a customer to check a box or something similar on each coupon they want, and when they have finished, they generate a single page that has all of the chosen coupons ready to print as one document.

I'm trying to convince her to use drupal as the framework for the site. If I can show her this functionality in action, I think she would go for it and it would be a huge improvement to the whole project. I'm sure drupal has this capability, and like most things there are probably multiple ways to accomplish it. I was hoping someone might be able to point me in the right direction as far as modules to consider or different ways to achieve this functionality.

I hope this is the right section of the forum to ask about this. It's sort of a "recipe" question, and it seemed others were asking those types of questions here. Feel free to move the topic or let me know where it should be.

Any guidance or recommendations that anyone can offer would be greatly appreciated. Thank you.
