Thanks all, I printed the petsmart.com Oceanic 90G salt for $19.99. Brought the printout to the first Petsmart store, the lady manager did not honor the price. The store price is $29.99. I brought the printout to second store, this manager happy to honor the $19.99 price. I picked up two bottles 90Gx2 and paid $43+ incl tax. I am happy. Very excited, first time to use Oceanic salt, been using IO for last 2+ years...
