I was a manager at staples back when i was 18. We were allowed to sell the demos.
If it was an active item, we just had to put a new one back out there from our next stock order. If it was discontinued, then who cares if we sell it.
All, demo's WERE NOT sold to the store, so we still had to save all the software and boxes that came with it. Customers could still get rebates becasue of this.
I do not know of one store in my area (office max, Office Depot, or Staples) that does it diffrently. Turns out maybe CC does it diffrently.
But the local CC here, has the same policy as my old job does.
Well good luck.
