strategy Your best advice for end user negotiation succesful sale.

[Chill Names]

Greetings:
All threads I have read here on NP when you have an inbound inquiry it is best to let the customer wait some time to reply in order to see their hungry about getting that domain. Ok.
What about end users outbound?

Is it better, when they reply for an asking price or whatever they are asking, let them wait a few? Hours? Days? I know your risk of loosing that sale but what do you think? Do you usually let outbound inquiries wait some time?
Real experiences and advices are appreciated.

Thank you-
