I originally called JAX and they hassled me, but I finally go them to set up a request. I asked for two large dust bags and got one medium (it just showed up the mail yesterday, after a couple of weeks). Unfortunately, it doesn't fit my bags. However, at the store, I explained my issue, and they gave me 3 large dust bags...absolutely no problem! Just tell them the size you need and that you didn't get it with your bag, and they will usually do it no problem if they have extras in the back. I also asked for one of the small white belt dust bags for the capacity wristlet that I bought, and no problems with that either. The only problem was that they totally screwed up my order (which is another story)...wrong wristlet and the platinum Bridgit was missing the metal snap logo that's with the hangtag! Sadly I didn't realize this till driving back home (an hour away)....
