Hi Kerry
People here are pleased/excited by what they have discovered and have been willing to use credits for what is a test run. There have been no concessions whatsoever, as far as I can see.
Yes they need to cover their costs, but not on a test run.(Maybe half price

). It smacks of trying to get in some return as quickly as possible. We are the guinea pigs and we have to pay for the privilege. It's not professional.
Me thinks I might have a bit to say to them - Maybe Christmas afternoon
