Really depends on the clients but I like to give them something they will definitely remember. I am a big fan of giving grill as gifts. They have a BIG impact, especially when I drive up with a trailer to personally deliver it. Or if no one is home I will leave it on the deck or patio with a giant red bow and a thank you card. I have also given a lot of Home Warranties for older homes or homes with older systems and appliances. It gives the client "piece of mind" and if anything does go wrong we come out looking like heroes!
