PureMixer commission is one of the lowest on the market!
It varies from 0.5% to 2.5% + 0.0005 BTC per each target address.
Please, note that when filling out a mixing request, the commissions end not in round values, but in pennies.
This is done in order to make it much more difficult to control and track your final amount of BTC at the
output.
Commission control - available.
