I ask these questions and it works well:

1) What is a price for this product that would be too low for you to trust?

2) What is a maximum price for this product that would that would still seem like good value?

3) What would be a maximum possible price for a this product?

They can help to get you to a good starting point regarding your pricing strategy.
