If you order ONE gallon of Muck these days and ship it via Priority Mail the cost of shipping will be approximately $27.00.  On the other hand we have discovered that we can fit TWO gallons of Muck in the same Priority Mail Large Flat Rate Box we would use to send a single gallon and the shipping cost will still be just $27.00.  If you need more than 2 gallons of Muck you cannot use this item code or the website will miscalculate the shipping cost.  Each TWO Pack must be ordered separately or you can order a four-pack of Muck gallons and have them shipped via UPS for a shipping cost of about $42.00
