There are 2 coupons on this printable page from Giant Tiger. One is for a $10 discount on a $50 spend and the other is for a $25 discount on a $100 spend. That’s not a bad discount really!
They both expire on the 31st of December 2008, so you should use these soon!!
Their store locator is on the right hand side of the Giant Tiger web page.
Thanks for the pic J.Derikozis!
