I've attended trade shows many times when I was still working with my former boss,who is a jewelry designer. Every week they always have shows and a few things we had as promotional items were pens and grab bags. We would normally include a pair of earrings in the grab bag and designed the pen with a company logo on it. People love it every week co'z we really put an effort to our free items. Be creative do something fun,unique and rare. I stumbled upon this one website,that has top selling promotional products from cellphone/business card holder,dart pen,computer brush,lunch sack,ornaments,to mugs and many more. You know these would really caught people's attention. Gimmees has tons of these products to choose from. Guaranteed great service and great products that everyone will really enjoy.
