I help my husband run his convenience store. Every Valentine’s Day, I go to Walmart or some such, buy a large stuffed animal and box of chocolates, go to the dollar store and buy some swag to put on the stuffed animal, and run a fb promo. You must “like” the page to be entered and the winner is determined by a random number generator. I also display the animal in the store with a sign around its neck with the same message. Each year I get hundreds of new followers for less than fifty bucks. I am not sure if this translates into sales but it creates quite a buzz and sets us apart from other, similar businesses who do not do anything like this. I do believe it pays off quite a bit in the long run.
