Stop in for a cup of coffee
One of my customers is a marine. He bought their wedding ring from me before he was deployed to Afghanistan. He made arrangements with me and sent me payments for some nice diamond earrings for his wife. Then he called her and had her stop by "to get her ring checked". He called her from Iraq while she was in the store and we presented her earrings as well as her favorite german chocolate frosting (no cake) and a candle with her birthday number on top. Yes, she cried. Later we recieved a package from him. He had a flight dedicated to our store, which I proudly display to this day.
