Ordered three pack - but the other ones were on sale too. Also when you check out, it gives the option of adding another item on for 30% off! I can't wait to try this. I'm going to use it first because I feel like it will help strengthen things up, maybe just an hour or so a day at first and then work up to the Mastic gum. Can't wait to tell you all of I see results, and let me know if you got a good routine down
