When I was at TW 'real' ILS approaches were not charged ie those done due to Wx. Practice ILS approaches were charged.
Coincidently, the VOR/DME approach for that runway has the same alignment, hold etc etc BUT practice VOR approaches weren't charged.
If one were smart one could request a practice VOR/DME but follow the ILS indications...
