Hey there. I've seen this at the Ulta in the Metroplex (plymouth meeting area). However, so that you don't waste a trip, you can call and verify that they have some in stock.
Also -- I brought the Sallys version of this when it was on sale a few weeks ago and it worked well. But..I've never used the official PM version so I don't know how it would compare.
Hope this helps ! Take Care.
