This has happened to me personally 2 times.How does everyone feel about a seller who sells to a 2nd person while you were trying set a time & place with them?
It ****'s me off of course because my word is my bond as it should be.
But again it is up to the seller who what when and where.
I do know that 1 of those times the seller was made a better offer and the seller took it. People are gonna people. They just can not help it and some people will drop their Mom in the grease for a better margin.
