Even with private feedback you can still buy,but don't be surprised if sellers block you. My first thought is what have you got to hide, and I am sure that most other sellers think the same.
I certainly never leave feedback for anyone with Private Feedback, what is the point. Feedback is for others to see how you perform, admittedly it is of no use really as no buyer can get a real Negative, but feedback left by a buyer tells more about them than feedback received.
