There is a bug that allows sales to go into deficit however if that was the issue here they would have no product to sell you provided you FE so I suspect they are being somewhat disingenuous in what they are saying. I do however have a lot of sympathy for vendors and buyers alike right now, the instability in the bitcoin market combined with all the other challenges has and will put many vendors out of business so please go easy on them. I'm not advocating people just FE for vendors by the way, that is a personal choice made by the buyer. I'm just saying please have some perspective, times are tough out there. Synergy
