Ask HN: Can 20x price difference hurt us?

We are https://extracttable.com - an API service to extract tabular data from images and PDFs. Recently we tested an approach to speed up the current process, amazingly, it is cutting our operational cost to 40%.

Considering 17% of current users have re-purchased the credits and the other 83% users who are yet to completely utilize credits of their first purchase - Should we consider to revise our price (slash by 30-35%) to the user, which is already 4-20x cheaper than our competitors. Can it help to attract more customers? or give a negative affect?
