Promotional porducts

Hi Mates
Do you know how to use printed promotional products ? I am a business development officer and sometime this question is asked to me by my clients. Some starter business men don't know how to use promotional gift products and advertisement gifts. So I have started this thread for all of them who are starters and need suggestions over it. You can use printed gift items like notepad, balloon and t-shirt as a advertisement gift of your company and a most popular business promotional gift is none other than your business card, by distributing these gifts you can increase your business popularity.
