Is it possible to receive only one payment for multiple submissions?

I want to charge say $5 for each form submission. If a person wants to submit 4 forms I do not want 4 payments of $5, I want one payment of $20 through paypal. Please inform if this can be done.

Hello Bernie,

As far as I understand, you want to receive only one payment for multiple submissions. Unfortunately, this is not possible. 

You can receive payments for each form, separately. You can not receive total payments for more than one submission.

Thanks.
