While I was at Walmart in Eddystone, I checked out the canning supplies. These are located in the kitchen section across from the vacuum cleaners.
I found both Ball jars and Golden Blossom jars. The Ball jars came in a variety of sizes with both wide mouths and regular mouths. The Golden Blossom ones only came in regular size pints and quarts. The Golden Blossom ones ran about $1 less than the Ball jars, with the prices marked on the white and yellow stickers on the packages. I think the pints were $6.88 and the quarts were $7.88.
Walmart is also carrying boxes of regular and wide mouth lids, and boxes of both sizes with bands and lids. I also saw a package of canning supplies – funnel and jar lifter. In addition, I saw two different brands of pectin for making jams and jellies, containers of pickling salt, and boxes of the white plastic lids.
Nearby was a 16 quart pressure canner made by Presto.
Just a note for those who may have found a Presto pressure canner at a garage sale this spring: Do spend money to replace the rubber ring, and the pop-up part. You’ll thank me for it when the lid seals correctly when you’re pressure canning. Just find the model number on the canner and do a search online. Amazon is a possible resource for the newer Presto models. For older one like mine, I had no problem finding the parts at a distributor. The ring was sold separately and the pop-up part came as part of a set.
