Well I have already spoken to a few taxi drivers about promoting my products in their cabs for a commission. So it is good for that but, in essence it is also good branding idea. As you said there is little else to look at in a traffic jam, not many people would refuse a free air freshener and it produces great connotations with your brand as it is related to a great smell.
A nice little light bulb moment there thanks for sharing![]()
Generally they start at about 500 pieces and around the 70p mark. Bespoke shapes and full colour can change things but this type of thing all depends on your needs. Don't think the OP's idea of Baby related sales should be scent led. Automatic smells you think of when thinking of babies is poo and puke. Might not be to successful but I am sure they would remember you for it.
I have just recently bought in a new type of freshener that we can print in-house to whatever design and quantity we need. We can also add any scent that we can get our hands on. They aren't the usual pulp board type but are material based. Haven't really tried them yet as we are so busy but you have reminded me to try them out as they would be a huge seller for us if any good.
