Guys, just curious what you feel the right pricing structure would be. There is an increased cost to us for additional sites, but it is NOT the retail price of the plugin.

At the same time, we want to keep pricing very, very simple. So far, how we've done this is as volume discounting (of up to 90% off). Combined with annual payments, this can mean for folk with dozens or hundreds of installs, the per-site cost is under $2/month (or lower in the case of a recent price for 2,000 sites).

Very open to thoughts!
