When you are at a convention of at an event where there is more than one competitor or exhibition, it is difficult to say whether you are giving out your promotional products in vain or if they will actually bear fruit. When you print promotional products you have to make sure that you use your budget effectively. If your item costs you too much then you won’t be able to have a big enough supply to beat the law of averages and if you spend too little per item, you might end up with something that doesn’t work and which will give you a bad reputation. Spend what you have wisely and give out your item when it looks like someone is actually showing interest in what you have to say. Giving out your products too freely might see you at the end of the day with nothing left to give to someone who is truly interested in what you have to say or sell.
