I did not, firstly because I have no way to verify that the email I'm contacting is not some sort of scam to get my info, and secondly I don't have time to sit and
have a back and forth email conversation to maybe potentially buy the domain for more than the current value. (Yes, value depends on what someone is willing to pay etc)
Whilst it was frustrating they were not available, it wasn't the end of the world to me.
The people owning these domains most probably have them listed on a domain market place so you might not have to deal with the person directly and if it's listed as instant buy there is no bargaining or whatnot. You just buy it and the platform handles the transfer of ownership.
