Well Woot, I tried really hard to buy one of these and other Logitech peripherals tonight, but whether I used the app or the website Amazon Pay would time out with a “504 Gateway Time-Out” error. I tried on WiFi and on cellular, so it’s not my connection. Guess I’ll hope that some of these (and my other items) are still left when I wake up in the morning 
Hello. We had some site issues around that time. Should be good now.
