title: Suggestions for a "shopping cart" application with a twist?
body: <p>My company wants users to be able to gather different documents from our website (for instance, manuals, installation instructions, etc) and put them all in one place (kind of like a shopping cart) to then print out all at once when their visit is over. Are there any applications that I can leverage to do this? We want something that's fairly plug-and-play because this is a late-stage requirement. I feel like I've come across something like this before but can't remember where. </p>
  
  <p>Any suggestions would be greatly appreciated! Thanks!</p>
