Exactly Shady Sue,
We are image exclusive only as are just about every stock agency, I would never put all my eggs in one basket I even tell our contributors the same thing " Don't put all your work at Spaces ". The one part of your view that I question is that the store controls the price of what we sell our images for that is not the case. In multi distribution in Macro you set the price and every distributor has to follow that price, it cannot be changed by the distributor.
Thanks for the feedback,
