When I was trying to order a charger, I noticed that they would be in stock a good 24 hours before the notification e-mail went out. I wouldn't rely on the e-mail. You might just have to do a daily check. That is what I did when I was waiting for the one with the 18 foot cable to get back in stock. Also, I would recommend measuring your charge location to where you anticipate your charging port will be. The 18 foot is a bit tight since I put the charger centered in the back of my garage. Right now I have to back in or support the cable from my garage door track to keep it from putting to much pressure on the handle plugged into the car. I really wish they had a 25 foot cable.
