Want to extend two licenses

Hi,

 

Okay, an answer to this question might invoke a bit of creativity.   

 

I've got two copies of NIS at home and my mother has a third copy (she lives about 30 miles away).   I have a copy due to expire on Sep. 4th and my mother's copy expires on Sep. 3rd.   I want to renew two licenses immediately (my copy and my mother's)

 

My mother's copy is not in my name at this time.

 

I want to renew both copies in my name and be the owner of all three (so that when I go to my account page I see all three).

 

What is the best way?   

 

My mother is 74 years old and can probably handle installation (including downloading a file) and being given a product key.

 

Any suggestions? 

 

David
