Shipping is by USPS Priority Mail. 1 jar approximate weight: 1 pound. The more you buy in a single shipment, the less it will cost per jar to ship. We can fit 6 jars in a $13.45 box. Shipping just one bottle costs us over $6.00. We try to charge only what it costs us to ship to you. Some combinations will charge too much for shipping. If that happens we will refund the difference. Email us with any questions you have before ordering.
