I have a scenario like, i need to supply price to user to purchase the product. So i used "Allow User Supplied Price" feature and i can manage it perfectly. But when zero price set to user it is not allowing to add to cart. It shows an error message like "Price contains invalid value." please suggest.

Have you looked into the "Allow 0 Dollar Orders" setting yet?

Thank you for the response. I already set Allow 0 Dollar Orders. But still getting error "Price contains invalid value." It works perfectly for products when "Allow User Supplied Price" is unchecked. But I need to configure zero price for products with "Allow User Supplied Price".

I haven't had a chance to formally review this use case. It may be something we might not want to completely support. I don't know yet. It may be best to create an issue so that we can look into this more formally.
