Paypal Transaction Fee and Invoicing?

BlazingBiz

Hey! I'm considering a move from Freshbooks to Wave. However, one thing I've really loved about Freshbooks is that they have a deal with PayPal that has a flat 50-cent fee on transactions (as opposed to the normal 2.9%). So no matter the size of my invoice, I only lose 50-cents off every invoice.

I had heard that Wave offers the same thing, but I can't find it anywhere? If you don't, that may be a deal breaker for me.
