It worked for me yesterday, 12/10. Call the 800 number and P&M and you may get some help.
One thing I learned is that Staples has multiple warehouses around the country, and the sorry dogs will not (willingly) ship an item from a remote warehouse if the one nearest you is OOS. They would rather disappoint a customer than incur a few $$$ of shipping cost.
However, if you complain loud enough, to a supervisor if necessary, they WILL cross-ship. If the website is still showing "1 day" availability, that means that at least one of the Staples warehouses has it in stock.
