Where to buy Denture cleaning tablets at lakeside

I need to get some denture cleaning tablets that fizz when you drop them into water. I looked in the dental section at WalMart and Soriana but didn't see any. Please tell me if you have found them and where in the store they are located

We buy Correga denture cleaning tablets at walmart regularly.
The are on the aisle with all the toothpastes.
The box is small, and not easy to see amongst everything else on the shelves.
Of course, they may have been out of stock when you looked.
One of the joys of the lakeside walmart.    

I found them at Wal Mart. Just didn't know what I was looking for. thanks.
