HST stands for Harmonized Sales Tax, and QST stands for—you guessed it— Québec Sales Tax. Ever think that they make grocery receipts as confusing as possible so you don't really understand what you're paying? Well, maybe they do. what are the tax codes on the receipt - really this should be printed at the bottom - i thought J was 8% (GST) but then that doesn't make sense. Our till receipts give you information about the products you've bought, details of when and where the transaction took place and the payment method you used. I have not been to RCSS for a while until today and I noticed the receipt has smaller fonts than usual.
