Let’s say you’re walking down the street. A twentie-something dude comes up to you – “hey, are you interested in a new iPhone 5? I’ll sell it to you for $20″. He pulls it out of his pocket and it looks legit. What do you do?
My guess is that you won’t buy it – even through the price is amazing and you know it’s a good product. Why not? Because of lack of trust. Does it work? Is it stolen? What if it breaks the next day? Why so cheap? You’ll get all these questions in your head and since you don’t know the guy, you’ll probably pass.
