There is an excellent price on Tide but it appears the sale is today only. You can get 150oz of Tide (96 loads) for $9.97. That works out to about $.06 per oz. That beats Target, Walmart and even Costco with a sale.
The limit is 10 and you can order online and pick up at your convenience. I ordered 3 to pick up and that should last us for quite awhile.
Please note the sale is while supplies last and may end at any time. You can also call your local store and ask what availability might be if your zip code is not showing up for pick or delivery options.
