Canadian Tire is having another scratch & save event this Friday, Saturday & Sunday (May 18-20). You should get your scratch card in your local flyer.
Prizes are:
1) $5000 CDN Tire gift card
2) $5 off your purchase
3) $5 M&M meats coupon
If you do the flashlight trick to see what's under the scratch area, the last 4 digits in the bar code can tell you what you've won. The ink is kinda light, so it may be easier to look at the barcode itself (on the far right).
1) 5622 = $5 off, barcode: two thick lines followed by two thin lines
2) 5630 = $5 M&M coupon: 4 thin lines
