Update: Sold out again.
I don’t say this lightly, but Amazon’s running an extremely exciting deal on Cascade’s top-tier Platinum Plus dishwasher tabs right now, bringing the $20 tub down to just $11.
It’s actually three stacking discounts in one. First, clip the $3 coupon on the page. Then at checkout, use promo codes PNG20OFF and 2PLATPLUS to save an additional $6. That’s less than $.16 per load for some of the best dishwasher detergent you can buy.
