Gitchers is an online database of people (and dogs*) who want free t-shirts. You enter your name fr a free shirt, then businesses search through the listings. If chosen, you get a t-shirt in the mail.

Businesses get a unique advertising opportunity and people (and dogs*) get a free t-shirt. Check them out.

*Gitchers even lets people request t-shirts for their dogs.

Implications - People love getting free things, even if it is something little. A business that gives away its items or services in samples exemplifies a great way to gain public attention. Often times, people will try a sample, realize they like it and will buy the product or service when the free sample runs out.
