Bulk Barn Nortown Shopping Centre

I have a receipt, spent $17.15 before taxes. Receipt has printing at the bottom. Printed are these words, "Hand in this receipt for more goodies: next part tells you to bring this receipt in during the period of, Aug 31-Sept 6. I did that and was told that to get the goodies, a five dollar gift card, spend another fifteen dollars before taxes. Point out to the member of staff that it says THIS receipt.....no, that receipt doesn't count, you need to spend another fifteen before taxes.
