La France as been discontiuned for ages, it's even hard to find NOS boxes.
Basically Dial Corp bought the brand from the company that was making it,but that company continued to produce the product. All at once the company stopped production/closed up shop leaving Dial Corp basically empty handed. All that was left was what was in stock/distribution/stores, once that went that was all she wrote.
Every now and then you can find various vintages of La France on eBay, and or estate sales/thrifts.
