While they do have canning and pickling supplies, canning technique, recipes and even a canning forum, they offer so much more. Among other things they sell garden seeds, kitchen essentials, gift ideas, and even large appliances.
I have only purchased a case of 12 ball 1/2 pint wide mouth mason jars. I am sure they will not be my only purchases. Although I can find all my needs here and for what I need the prices are rather reasonable, I feel the shipping cost is a bit high. After seeing this at the bottom of the page "Important mason jar shipping notes: Occasionally a canning jar or two per case are broken during shipment. Please DO NOT refuse delivery of shipments with broken canning jars. It is generally far more cost effective for us to refund the cost of the damaged jars or send replacements than to pay for both return shipping and reshipment of the entire order." I was so glad that I read that because one of my mason jars was broken and another with a huge crack in it when my order arrived. I called the company and within the week I had the replacement of the two jars.
