Hurry and print a high-value $3.00 coupon for Tide or Gain. Use this coupon at Walmart on a 100-ounce bottle of Gain that’s on rollback for $8.94. Apply the $3.00 coupon and pay $5.94. That’s one of the lowest prices I’ve seen! Save on Tide, too. A 100-ounce bottle is regularly $11.97. After the coupon savings, pay $8.97.
