Really? Is that really the attitude you want your audience to take? That they should be wary of what you say and what you offer and what you promise?
How about “buyer trust”?
How do you deal with customer disappointment or buyer remorse? It’s the difference between “tough luck, you should have read the fine print” and “oh no! How can we help?” If people know you will always make it right, they will beware less and trust more.
What do you have to do to create trust? How much would it cost and how often can you produce it?
Whatever it costs, it’s a bargain.
