Oikos Canada has a coupon available through their website for $1 off the purchase of any Oikos product, including the new limited edition pink lemonade flavour! This printable coupon can be found through the link below.
There have been coupons available through the Oikos Canada website each month for some time, however, it used to be the case that you could print only one per month. You can now print it four times per email/browser each month. The expiry date will depend on when the coupon is printed, but it is usually valid for about thirty days.
The four pack of Oikos yogurt is currently three for $10 at Walmart Canada, so if you print and use three coupons you can get three for $7, or just $2.33 each.
