Okay all you DIS experts...I saw someone post where they bought tide tablets for the washing machine for vacations as you can easily transport them. Where do you all buy them???? I just shopped our local Wal-Mart and Wal-Greens and could not find them at either place. Please help!! Also, does anyone know how much they cost? Any other ideas are welcome as I really don't want to lug the huge bottle (from home) to Florida.
