Yes, sounds like you are being looted.
Look at h-1b data collection form.
Between question 8 and question 9; it says if you answered yes to any of the questions before 9 then you only submit $190.
Question 4 asks for yes/no answer. Question is; is this the second or subsequent request for extension that you have filed for this alien?
If you answer yes; ie., it is third h-1 for the beneficiary from the same company then you only pay $190.
If answers are "no" then in question 9 it asks for number of employees. If over 25 then pay additional $1,500. If less then 25 then $750.
After 9 there is a "note" which says if you are seeking intial approval or approval for an employee currently working for someone else then pay additional $500.
