I NEED TO BE ABLE TO ORDER MORE THAN 6 SENSORS AT A TIME, I HAVE LEARNED FROM THE PAST THAT IF YOU ORDER MORE THAN 6 SENSOR, YOUR ORDER GETS DELAYED, THAT'S VERY ANNOYING.

Good prices and easy ordering process (order #18003). The only issue that I had was after placing the order, completing the entire process, I received three emails stating that "We noticed that you started checking out on our site, but didn't quite finish the process". After calling customer service, they ensured me that the order was complete. Since then, I receive the same email(3 emails at a time) on a daily basis. Just a little annoying, but easy enough to delete.
