I know my husband, my son, my postman, my optician are not people who are likey to buy my stamps. This is just the same as being at a business network. But they say the average person knows a 100 people. So every person you meet every day know a hundred other people who might buy what you sell.
So am I saying every person you meet has to understand the minutest detail of what you do? of course not, but would be great if they know what you do in general terms and know how to contact you, have you made that easy?
