Costco’s signature brand, Kirkland Signature, has a special discount deal on their Eco-friendly laundry detergent brand. From May 23rd until June 17th, 2018, you can get a $3 off discount on
Kirkland Signature Ultra Clean or Free and Clear Liquid Laundry Detergent. You can find this offer in their stores or buy it online at this or this page.
Currently, the bottle that this product comes in offers an additional 5% of product for no additional cost, making this discount an even slicker deal.
The detergent is non-toxic and has less impact on the environment. Each large size bottle is enough to wash 126 loads of laundry. The product is concentrated, so 126 loads of laundry for one bottle is on the high side in contrast to traditional laundry detergents.
To redeem the special discount, you should have the Costco app installed on your smartphone, and then show the coupon on the app to your cashier at checkout. The app is available for free in the Google Play store, the Kindle App store or through the Apple App Store.
