I've been considering experiencing a duo.  There are a few ladies I have seen that perform duos, so that will make it easier. The question I have is, when a lady list a duo donation is that her half of the donation or the total donation?  Is it better that I ask them directly?

website or in their ad. Some ladies who have a specific duo partner will list the duo rate, while others will list their rate and then you ad the rate of the 2nd provider and you know your total.  

In either case, each provider's gift should be in a separate envelope.
