Robert: I just arrived to my office to prepare everything. I’ll let you know which stones I choose.
Harry: Ok. Perfect
Robert: Once you told me that I have extra 5% discount for the white stones. Is it included in the list?
Harry: I told you that you have extra 2% off.
Harry: And that will be discounted once you choose the stones.
Robert: Ok. Is it included in the list? ;-)
Harry: Not yet in the list.
Robert: Aaah ok. So first I need to chose them.
Robert: Got it. Thanks.
Harry: No problem. If you prefer me to add it directly next time please let me know and I’ll do that from now on.
Robert: I sent a list with certificate numbers. Send me the invoice please ☺
Harry: I’ll prepare the invoice tomorrow.
Robert: Ok
Robert: Thank you. 
Robert has extra 2% off for a selection of stones.
