I'm not a coupon blogger. I'm not even a regular coupon user. I don't subscribe to the newspaper and buy so few name brand products that searching and clipping is a waste of time to me. However, this week I was sitting around my parent's house on Sunday (6-27) and paged through the coupon inserts. In the Redplum insert, there is a coupon for $3 off 2 cases of Ball or Kerr Jars, any size. Another coupon is good for buy two get one free any size lids or lids and rings. The rings coupon has a printable version too.
When shopping at my local Kroger (another thing I don't do regularly) I discovered they had jars and rings on sale. Using coupons I saved over 30% off full price. This might not be the absolute cheapest you can buy jars, but it's a very good price. I noticed at Big Lots that their Golden Harvest brand half pints were 12 for $7, a bit more expensive than this coupon deal.
Here's the scenario:
2 x Ball jars, 12 half pints, at $7.81 ($1.38 off at Kroger) = $15.62
subtract $3 off coupon = $12.62, or 53 cents each
Regular price = 9.19 x 2 = $18.38, or 77 cents each
3 x 12 Ball lids, regular mouth size, at $1.78 ($0.31 off at Kroger) = $5.34
subtract $1.78 for one free = $3.56, or 10 cents each
Regular price = $2.09 x 3 = $ 6.27, or 17 cents each
