Give a staff member who has never had responsibility for purchasing stock up to $500 to spend on a new product for your business.
Tell them to find new products you have never sold that they think will help attract new shoppers to the business.
Stay out of their way. Let them spend the money, price the goods, display them and promote them outside the business. And watch what happens.
Hopefully you and your staff member learn plenty from which both of you benefit as well as the business benefiting.
Sure its a risk but is it any worse than plenty of products you have spent money in your shop on are performing today?
