Whenever people think of contests, they usually think they need a grand prize. Instead of a contest for one prize, why not ask your customers for some feedback and reward them with a special offer or gift. Imagine a bakery giving away 100 Valentine Cup Cakes. All they ask you to do is tell them what you find most memorable about their bakery. Wouldn't you rather look through 100 Entry Forms telling you your bakery has 'great design'...'very creative'...'the counter lady is precious'. Think of all those testimonials you can post on your Facebook page and website.
Imagine how happy you'd be to give those 100 customers a cup cake and a smile! Come on...you've got time. Make it happen!
