Another member tried it a few times, before it finally worked for her.
If it won't for you after several tries though, yep...I'd give them a call. They've been very helpful when I've called with questions or a website problem.
In the end I went ahead and got them without the code. If you click on the top of the screen where it says VD10 you get a listing of items that is a subset of their complete inventory. The nautilus coils aren't on that list. Some other Aspire heads were on the list. It said something about the clearance code being related to a warehouse reorganization. Maybe they took the Nautilus coils off that list. Still the cheapest price around I think. With all the crap going around I'm just glad to have them.
Got enough now to keep my wife going for 6 years. Beyond that she will have to use KFL or Lemos I guess. I'm trying to be sensible about this stuff.
