I think it depends on where you are. Around here they're getting to be pretty easy to get ahold of if you know when the shipment is coming in and drop by when the store opens (no crazy lines or anything though).
My brother said they have a bunch of them at the stores just outside of Milwaukee. So it just seems to be a regional thing I think. They sell out pretty quickly but you should be able to get one with a little bit of driving and planning.
