Good luck cancelling with HP’s customer service. Keep in mind they may charge a 15% restocking fee if cancelled after 1 hour and they might still ship it and have you wait until it arrives before initiating a return. I had a pop up say my order didn’t go through, ordered again, ended up with duplicate orders, received login errors to the website preventing me from cancelling within the first hour, and was told my cancellation request failed 3 days after I submitted it and that both will be shipped, yet they still haven’t even finished building it…
