I have some persons who all they do is price, from time to time they message me asking for the price of a particular product or services. After agreeing on a price which they themselves even agree that it is a fair price, they tell me they would get back to me only for them to do it else well or not at all. How do you handle such customers? Do you keep answering them with the hopes that they will patronize you one day or do I start ignoring them.
