As I learned from a very knowledgable clerk today, all 'called back' inventory, once it is off the shelf and boxed in the back, is not allowed to be sold. Period. Their stock was awaiting return.
The clerk also informed me that once stock (he used old software as an example) is deemed 'called back' it is returned to the Toronto distribution centre... for destruction !
I had told the clerk that I was prepared to make the long drive tonight to check out the stock that was showing online... then I got the inside info and suggestions for potential other sources (which I know don't have any) so I believe his information is accurate.
At least 7 clerks at various BB's around the GTA have used the term 'called back' when I inquired, and based on what I haven't seen in the stores that used to be there, it makes sense.
