Cash Register App?

[stimits]

Hi,
 
Browsing through some of the setup for the demo data, I'm wondering if there is 
a specific app which would demonstrate what a salesman at a cash register might 
use for a retail customer in the store buying something? There seems to be a 
lot of ability to add and set up the store and various products, but I'm 
wondering if there is something specifically representing an actual in-store 
sale? Is there a simple default?
 
Thanks!
