How to exempt myself from paying for my own SaaS product on AWS Marketplace?

I am developing a SaaS product for AWS Marketplace with contract pricing. I initially set the price very low and tested the integration with AWS MP. I now want to update the pricing and release the product (set visibility to public) but how will I test and debug integration issues in future? If I subscribe to the product, I have to pay for my own product which is wrong. Am I missing something? Can someone please advise?
