Also, looking for the price (and how) to add custom domains.  https://app.unbounce.com/myuserid/domains  does not show any way to add new/additional domains.

Hi Michael, 

If you want to add an extra domain:

1. 
   

   Open up the page you want to use with the new domain

   
   


2. 
   

   Click on “Change URL”

   
   


3. 
   

   From the drop down options select “Add a New Domain” 

   
   


4. 
   

   Follow the prompts 

   
   

As far as pricing goes, I believe it was $10 per month for each additional domain but might be wrong on that one. 

In any case, if you visit your Account panel, you’ll be able to see how many domains you have and how much it would cost. 

Best,

Hristian

P.S. Attached is a screenshot of the above explanation

OK, found it - thanks.   The actual cost is $5 for a new custom domain (at least on Pro Plan as of Aug 26, 2016)
