This tool provides an ESTIMATED FREIGHT COST ONLY! We cannot 100% guarantee it's accuracy due to many unpredictable factors. (i.e. beyond points, rural areas, fuel surcharges, etc.) It generates an estimated cost PER CASE. Regardless of the exact number of pieces you plan to order, shipping costs must be based on OUR CASE PACKS for accuracy. So ROUND UP your number of cases to the next case pack to include your order quantity. EXAMPLE: if our case pack is 42 and you wish to order 60 pieces ( 18 pieces more than a case) multiply the shipping cost PER CASE x 2 for an accurate estimate. Bottom line, ordering in OUR CASE PACK QUANTITIES will maximize your investment and minimize your shipping.
