I just sent the WC I have been working with an email about the OOT bags so I will let you know what she says.
As for the additional costs popping up, I have just made sure to ask every question I can think of to get the answers in writing so that they can't change anything on me in the future! I am pretty sure both my TA and the WC never want to hear from me again, but I don't want any surprised coming up!
