Why do these firms give me their material for free?

Because I promote them just by biking with their products but especially through publications in medias such as articels in newspapers and magazines with pictures of their products in action.

Slides of this kind I`ll give them for their use in their advertisements as well - so itīs a business of giving and taking on both sides.
