I checked the website and I cannot find anywhere it says that the 2% deposit fee is in place before you actually start the mixing process.

Mixing fee is 2% of deposited amount.
It's there in plain sight just above your deposit address, you can't miss it
but I'm still waiting for the answers to my questions on when and how the fee will be applied?
so for example I deposited 0.006 then fee will be 0.00012 and I will lose another 0.00088 
but if I choose voucher, redeem later, I will not get charged the 2% fee?
