Most every business needs a great name badge. Name badges are the only product that I can think of that you only need to sell once and then you just take reorders.
I recommend you sublimate your reorder information on the back side along with important information, such as a mission statement or emergency contact information. The back side does sublimate well enough for this. For the front side, I recommend you reserve the lower third of the name badge for current specials or promotions. By turning the name badge into a walking billboard, the business will value it higher, and for you, they will likely replace the badge more often with a new promotion.
