Yes, that's what was happening to me, except in reverse. I was hoping that in this "trusted network of peers", the seller would be more assertive about communicating that to me and qualifying the purchase based on actual market price at time of sell, even if that meant we would have to cancel the initial deal and re-do it at that time. But, that would require them to hit the reply button and engage with me to negotiate terms and determine my seriousness as a buyer, if that is an issue for them.
But, instead I got crickets for a day or two and then an email that they were sold out, like with 4 people in a row.
