Head's up for anyone who is gluten free: I was at the Ajax store and found all of the gluten free shelf 40% off or more. For example, Catelli pasta $1.27, Glutino pretzels $2.98, Kinnicks' cake mixes for $2.33 and Rice Krispies for $2.49 a box. I stocked up for little man and I, but I left lots too! 

Don't know if the Oshawa store is the same, but it maybe worth a call.
