need help with escalation clause in north carolina

[Anna Stratton]

hello all.

I submitted a contract for my first ever deal. the buyer then said "highest and best tomorrow".  I ask my agent about an escalation clause and she said it was not supported by the real-estate commission and that the seller and buyer would not likely know what that was.  any ideas as to how to proceed? should I insist on putting the clause in (which is what I think I should do) and my agent should educate the others? should I just put in my best bid?  has anyone done this in north Carolina?  bid due by noon tomorrow
