This reminds me of time I tried to get permits to hike Half Dome. I had heard they go pretty quick so I had my computer at the site as soon as they became available. I hit the day and the number of permits I wanted, clicked enter and, when everything was refreshed all the permits were gone! They had 300 available for each day. Our whole vacation had been planned around that date.
I did a little more research and found a board where people were selling them for the face value (1.50) and was able to get 4 permits for a day that was close enough to ours - so it worked out after all. Crazy! Okay I've digressed.....now back to your regular topic.....
