So I added an $8.79 ENJA CD to my pre-existing order of the October/November BN's, as it showed no additional shipping charge. What they did, rather than charge me the additional $8.79, was to cancel my original order and re-do an order with the additional CD, which came out to $18.75 more, I guess due to the change in exchange rates since I placed the last order. So I have buyer's remorse on that one, and won't do that again.
