I just sent another claim in for $40 more.
I had to ponder a bit with that one as I could have instead been up-decked one more deck. I figure I can walk up one deck for $40. If it drops again I will probably take the up-deck if it gets me where I really want to be...Mid-Ship Empress.
They are giving me price reductions because I haven't paid the final payment. When I do and the price drops then the OBC's will kick in.
