Promotional products should be given with a greater purpose than to simply have something as a giveaway. We should be mindful that delegates attending meetings or conferences walk the minimum distance of a 5K marathon by the time their day is finished. And, at no point in the day has the excruciating long line up at the canteen ever seemed to get smaller.
So when contemplating a promotional product for this audience, I would urge you to consider a product that not only delivers your message as an exhibitor but also brings some element of comfort and/or convenience to the delegate! By doing so, you could hit a home run!
