I paid to have someone write some programming so that customers could do the following:

* Press a button to obtain a URL with their cart contents that they can then save or send to someone else or use on another computer
* Send the cart URL to their email

And I've also got it so if you are using a form for email, say "do you offer a discount" and you want the contents of their cart, you can do something like this:

https://formwebsite.com/form2342342342?cartid=<insert cart ID>

Let me know if you find a need for this...
