This is a “yes, but…” response: a counteroffer tactic that accepts a piece of the offer on the table, on the condition that you receive something you want in return. It works as follows: you are given a deal and told to accept it as is, but there is one term you cannot accept. Conditional acceptance is agreeing to accept the deal only if the term is changed to something agreeable for you. If your adversary is presenting you with a true ultimatum, don’t expect them to acquiesce, but if there is any room for negotiation, they will bite. You may request a sweetening of the pot, or add in.
