Query: Item is no longer available, but AmericanRX still hasn't removed it from their pages.

Even though this product has been off the market for quite some time, AmericanRx still has not removed it from their pages.They substituted another Alka Seltzer product without notification and then I had to incur the expense of returning the product to them. They did pay the original shipping costs.
