Query: Salt Free Pretzels

It had been more and more difficult to find decently priced Salt free pretzels in the stores. The price offered by the case plus the free shipping made it possible to have a continual supply of unsalted pretzels in the house, without paying an arm and a leg. The only problem was that, with the change of the expiration date on the credit card, Amazon's instructions resulted in my buying two cases instead of one. But, the product is worth the price.
