I managed to get two boxes at Costco so we are good. But it took me four stores to find them. I asked a pharmacist at Rite Aid and she gave me ten from their supply which was very nice of her.
I asked the pharmacist about them a few weeks ago and she ordered them and put them behind the counter so nobody would grab them, and then she called me to say she had them.
I also got some from Amazon before they totally disappeared.
