Don't despair, Spiritfilled. After many years of cruising, we finally got our first price drop last year -- to the tune of $1000 total. We were floored, to say the least!
bethmclean83, in our case (albeit limited), the price drop was noted before final payment was due, so our balance was simply adjusted. Our travel agent regularly checks for price drops and alerted us to them. Of course, it never hurts to check yourself every so often, as bbw187 noted.
