You see them everywhere, bags that people carry with them, grocery bags, bags from stores and elsewhere. They all have one thing in common, and that's a logo or corporate brand. Big businesses know how important branding is, and how bags can be a wonderful tool to carry their brand even further. When someone walks around the street with a bag that carries their logo or company name, then it's so much better than a fixed ad, because everyone that walks past them can see it. That's the concept behind promotional bags, and why there's so many benefits of using them.
