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 $8.00. We don't like this any better than you do! We try to charge only what it costs us to ship to you. After all, we are in the mustard business, not the shipping business. Some combinations will charge way too much for shipping. Sorry, it's not our fault. Computers. If that happens, don't freak out. We will refund the difference. Email us with any questions you have before ordering.
