We ship via UPS and they charge by weight and dimensions. Water weighs 8 lbs. per gallon. Our mixes weigh more than that. Include the glass bottle, packaging, and packing materials and a 32 oz. bottle of mix will weigh in at 4 lbs. and costs $18.38 to ship UPS Ground to Central Florida … for 1 bottle. This is why we offer the ½ case and full case specials that include shipping. Also, we have added “Free Shipping” for all orders over $50.
