I hear ya! right before canning season started I couldn't find any either! I had to buy jars with lids and rings. Finally my wife found some at are local Sur-fine. I keep checking all the time still hard to get. Ace hardware,Walmart,Val-U Home center IGA.Dollar Stores, Also check your local Craiglist
My family has canned thousands of quarts and pints over the years. Grandmothers, my mother, and Mrs Brownie. All would frown on reusing lids, or using a reusable lid. Ball ,Kerr, and Mason are the only ones I would use. Some sellers on EBay and Amazon are advertising that they have Ball and Kerr lids, but they are cheap knockoffs from China. Look at the reviews before you order.
