Shop for popcorn merchandisers to keep popcorn warm for hours at country fairs, circuses, stadiums and street parades. Instead of storing bags of popcorn, waiting for your customers to come, popcorn merchandisers enable you to display freshly popped popcorn and keep it warm and fresh for your customers to purchase on demand. Popcorn merchandisers are especially useful for supplemental or remote concession stands and are also great for keeping nachos and peanuts warm.
