Usurv charges for different levels of targeting e.g. interviewing females aged 18-29.  We do so because Usurv only approaches a smaller specific group.  In this case to do so we do not approach males or anyone over 29. 

We allow two levels of targeting and charge an extra .10p per respondent for our targeting options.

The additional charge is made as members of this group who were approached are then quarantined for a week and not available to other Usurv users.
