So, you can either get a leash for free or donate to charity for free.. Second bit sounds weird. Haha.
This is taken from the site:
PawClub is dedicated to providing reliable, unbiased, up to date information and tools to help dogs stay happy and healthy. As part of our focus on happy, healthy dogs, right now when you sign up to become a PawClub member, you will be given a choice of either receiving a free PawClub lead, or PawClub will donate $2 to Assistance Dogs Australia for you.
PS. Click 'sign up now' for a picture of the leash.
i got my lead last week and they are really good leads
