My neighbor is a reseller of Used Cell Phones.  He has his own booth at the flea market. He works Friday, Saturday and Sunday and earns a full time income.  People come and go each day at his booth.  He always has a steady stream of customers.  He’s been there a while and has developed a following.  Some people come to buy one, others to sell one.  Some just venture in just to browse and catch a glimpse of the perfect one they fall in love with.  He gives it to them for a fair price, gives his card with a 10% discount towards the next purchase.
