In the Food Basics flyer for the week of February the 7th to the 13th, Oxi-Clean is advertised for $1.99. This may be a little difficult to spot as it is not pictured, but as you can see in the picture above where the Clorox and Xtra are pictured, it also reads Oxi-Clean for $1.99
There is a printable coupon that is still available, valid for $2 off the purchase of any Oxi-Cean product. Print and use this coupon and your Oxi-Clean is free. It is a SmartSource coupon so beyond the limit of two prints per computer, you may be able to print more using different browsers, but keep in mind that Food Basics may limit the number of printable they will take.
