If a person approaches you to sell you something, it’s OK to walk away. If they come up to you in a shopping centre, in a car park, or they knock on your door at home, it’s OK to say no.

The seller might offer you a free gift, like an electronic tablet or a t-shirt. Or they might offer a payment plan to spread out the payments. But think about whether you really want or need what they are selling. Maybe you can get a better deal if you look online or visit a store.

If the seller is really pushy and doesn’t want you to take time to think about the offer, then they care more about making a sale than what is best for you.

If you don’t want salespeople coming to you home you can put a ‘Do Not Knock’ sticker on your front door. The stickers are free. Order online or call 131 882 to request a copy.

Salespeople who ignore a Do Not Knock sticker are breaking the law and may face a fine of up to $50,000.

If you don’t want salespeople to ring you, register your phone number on the government’s Do Not Call Register. It’s free to register.

If you have already bought something or signed a contract from a dodgy seller who approached you, please call CBS on 131 882 or fill in the reporting a dodgy seller who approached you uninvited form.
