You may want to check your local Big Lots
The local Big Lots sells Golden Harvest Mason jars quarts, pints and lids for considerably less then the Ball jars at the local Wall Mart
With the size of my garden this year I'll be buying lots of additional jars and the money adds up quick.
Wallmart does have some less expensive jars but after reading the box I think they are intended for hot water bath canning and not pressure canning.
Not sure of the reputation of the Golden Harvest jars but I have used them without problems in the past.
Anybody have a good source for Pectin? Shipping shouldn't be too bad for that.
