If you missed the previous sale of 0W40 4.4L jugs, the one litre size is going on sale starting May 8th -14th.
30% off, Reg $13.99 on sale for $9.79 / L
Not quite as good as the 40% off of the jugs...but a savings regardless.
If you have a smart phone, I highly recommend the Cdn Tire app that allows you to create your own "shopping list" and it will inform you days ahead of any sale on items on your list.
