I’ve been trying to buy this for a couple weeks now. The site says it is unavailable but will allow you to be notified via email when it is available. I’ve signed up for the notification several times now and I receive an email everyday saying ‘good news - the product you want is available’. I go to the website and again - it is unavailable. Endless cycle… of course I can find no phone number on the website. I can chat and have someone call - tried that once but could not understand the agent… oh well, guess that means I don’t need it… have had several Shark products that I have been very happy with.
