A ML charging you $30 for BBBJ is very rare. Most charge $50 for CBJ and not BBBJ! As for FS, its $100 or more.
Yes, I actually never had a bbbj for $30, they usually have a sequence, offer HJ usually 20 then next NHJ plus 30 to 50 , then bbj add another 30 so i usually get offer around that price 80 to 100 up to the point of bbbj then FS is another addition to payment.
