Seen some discussion on the web about this topic and thought it would be interesting to see what all we've experienced. When at a bridal show it is paramount IMO to close as many deals there on the spot while the bride-to-be is enamored with your offering.
Over the years I've used throw-ins to sweeten the deal. We used to use double prints a lot which we charged $25/hour for. Also when we charged for a prop box we threw those in.
We will be attending a few expos in the coming months and are going to be offering a social sharing kiosk to any bride that books their booth that day.
Do you have a sales method, special offer that has worked well for you at Bridal expos?
