Prices are from a HP communication sent to HP partners. My CEO (we're a HP partner) sent the document to the relevant staff. These prices are effective as of Wednesday, so expect all resellers to start selling at these prices. The communication also states that:
"Currently Accessory inventory is reasonably healthy and we encourage partners to take
advantage of the new pricing."
Have you seen any official communications from HP about refunding previous purchases to the fire sale prices? Amazon is being really reluctant about refunding, and an official communication from HP could be helpful.
Canadian distributors had no stock on accessories as of early this AM. I found the dock and keyboard at 2 different Staples stores. I got the last keyboard at one store. They also refunded me the difference in price on the case between last Saturday and today.
