Started at $75 and using the free zone trick with $5 step. When I come to the last chance, it was $90 declined. I make a bid for $100 and won. 32% off. Not a wonderful deal, but I understand that it was due to the quiet big conference I was attending, causing a temperary short in supply. Thus the deal may have less reference, one may still try for $80 or lower in general seasons.
