Depends on the city and store I would imagine.
But I believe they a whole lot easier now to snag one than the first couple months.
I bought my IPP roughly a month ago. Ordered online and did an in store pick up. When I was picking it up I asked if they had any. The sales person initially said no, but as I was finalizing my IPP purchase it popped up on her handheld that they did in fact have one left. I of course got it.
I've heard of some stores having 10+ in stock.
