Gentlemen (and Ladies) can I simply say that it seems obvious to me that if you definitely want something that is for sale, the best method of securing it and finalising the details is to CALL the listed phone numbers. This is why they are there!
Do not leave your phone number in a U2U asking the person who is selling to call you. This is generally not how things work.
If you want something YOU chase it.
