Thanks a ton. For anyone who is looking,here is what I found.
I calculated the cost of creating one of these liquids. 
The maximum cost per 30ml bottle is $10.06 (shipping costs included). See the next post for more prices. A 30ml bottle of Halo liquid costs $23.26 shipped. This is a savings of $13.20 per bottle, or 57%. Knowing this, even if Halo had a 2 for 1 sale, you would still be saving more money by DIYing your 
juice.
 Keep in mind that:
 * This is creating a 75%/25% PG to VG mixture at 18mg/ml strength
 * In the price above, flavoring is calculated at 15% (just to show maximum cost)
 * All shipping inclusions are calculated by only buying the 
essential items. (no gloves)
 * DIY ingredients calculated from myfreedomsmokes.com
 * This pricing assumes you are buying 1x5ml bottle of patriot 
juice. See next post.
Here is a spreadsheet with all the information.
Hope this helps!
