Amazon them selves say that you can hide pricing information and when you do on invoice they do not accept that and ask for further proff of tracation from your bank account. A total scam is going on. There is no alteration in the invoice only prices has been hide out. and this is what we have been facing for past few times until the invoices are not showing the prices invoices are not being accepted. More over this is a clear act of storing data to aproach the suppliers by Amazon them selves and take over business from rest of the sellers. What Amazon has been doing so far.
