Wow, is it fun when one of the people who replaced you contacts you on LinkedIn asking for help.
@drwho @laprice You might try https://bidwix.com/ instead of haggling -- interesting idea, basically just helps two parties negotiate the geometric means of their secret min/max limits.
Of course, it does *reveal* both parties' limits to each other, effectively, once the deal is made.
(If you like haggling, then never mind. But I hate it.)
