Prelude

Usually, promotion is at their discretion unless stated otherwise in writing.
Of course you can argue for it, just like everything else.  The difference is that T&T might not care about your loyalty, but Safeway and Save-on-foods would do the extra mile just for customer satisfaction purpose, not because they think you are right.

Save-on-foods even pricematch competitor for similar products (depending on the store manager) if you bring in the flyers, it's not policy, it's just for customer satisfaction.  T&T?  They just curse you behind your back.  

You shouldn't expect that much from T&T.
