I agree. It would be great to have access to the water in local stores. I, personally, prefer the Spirit water over the Hempd drinks. In terms of going for natural and health products, alkaline water or electrolyte water is something I buy regularly. The CBD waters are a great idea but for a health product, I prefer my waters, sparkling or flat, to not be sweetened.
And as for buying water, it's just easier to pick up in the store than ordering online. But that's just my preference.
