I have been in the mattress and furniture business for more then 20 years and I can tell you what has worked the best for us. What we do is dress up a man in a Gorilla costume and have him stand out front of our store holding a sale sign. it seems silly sure, but it seems to work like a charm.
We have been doing it for years. We also have a Gorilla Robot that we bought at Super Sign Factory com, which looks like a man in gorilla costume...it moves and waves, (very cool) We use in place of the human Gorilla on the weekends, or when he does not show up for work.,
Also we have had great luck using Air Dancer inflatables to get people to in the door. Those wacky waving arm flailing tube man get the jod done!!!
We buy the Air Dancers and Gorilla Robots at [link removed]. They seem to have the highest quality for the lowest prices. The Air Dancers from them seem to last a very long time, so for that reason they are very cheap way to advertise.
One more big thing that has worked real well for us is FREE HOT DOGS. For some reason Americans can not say no to a free hot dog!!! Just have a person stand out in front of your store with a sign that says free hot dogs. When the people come in for the free hot dogs try to build relationships with them. Then when they or there faimly or friends need furniture or mattresses they remember you, It is amazing the power of a free hot dog!!! It works great for us we do it a few time a year.
