I got the last one in one of the three stores in Tulsa just now.
I knew where they were in the store, there were none on the shelf. In fact, it appeared the little tag on the shelf was gone too! (ARGHHH!)
I asked one of the appliance area employees about them. He walked over to where they used to be, peeled back the shelf edging revealing the bar code/price tag. He scanned it and his computer said that they were 149.99, and that THERE WAS ONE IN THE BACK!
Don't give up if your store seems to be sold out -- ask around. FWIW, I may have found the only helpful guy employed by Target.
When I looked on Target.com and used the "Find it in a store" button, it stated that there was "limited availability" in this store. Hope that is helpful.
