I saw that there were services only for military or their family, and some for "other individuals". Is the car buying service only for military, or can anyone take advantage of it?
Anyone can use this service if you are a member of USAA. Anyone can join. They do offer some services, insurance, etc, that are restricted to military and their families. Check out this link to see who is eligible for what. (Also it's free to join). https://www.usaa.com/inet/ent_utils/...s_usaa_for_you
BTW, today they are showing $300 instead of $200 below invoice.
