I put in a few of those "notify me when item is in stock" requests about 6 months ago, but have since found what I was looking for. Guess I'll be getting some 'notifications'... someday. Elephants & computers never forget! LOL
I put a "notify me when they arrive" with B&H Gun Rack out for one of the extremely hard to find PMR 30s on 12/3/2011 and they notified me they were in and I bought one on 12/7/2011. It does work, but only with some I guess.
buds programs seem to be a little out of date with the times. I would email them notifying of their notification systems deficiencies. who knows, they might actually find and fix the problem and in the future you (and everyone else of course) will be notified in a timely manner.
