Amazon.ca has Gain 2X Hight Effciency Island Fresh 64 2.95L (Pack of 4) laundry detergent for just $4.46 (save 94% off).
This is an add-on program item, so you need to be making a purchase of $25 or more to be eligible to purchase. You’ll receive free shipping at that threshold as well.
Already says it’s unavailable on the website 🙁
Looks like a pricing error where they wanted $4.46 per unit and ended up with $4.46 for 4 instead. It’s listed on the site again, but now at around a $30 price point.
