Taken away gut pain

Thank you for putting out such an awesome pitcher. This will be my 4th order with Cerra Water and I need more filters but this time I want to order the 3 pack as I usually order 1 at a time lol.....I want to ask for a discount or a special offer on 3 filters. I am a very loyal customer and to me, there is no other water pitcher and filter out there. I can say that with all honesty because this water has taken away a constant pain I had in my gut after only 2 hours of consuming the water.
