The $20 is just part of the overhead. In three years the overhead drops by that sum. It is not much of an issue, imo.
What I would like to see is EDIG structure a deal whereby they get a small piece of the rental or advertising fees, thus yielding a recurring revenue stream.
Who knows, if that proves to be a significant revenue generator, they could lower the price of the units to help drive future sales volume.
Lots of options when you don`t have a middleman with which to deal.
