First you need to get the coupons.
Where can you gather them from in Canada?
1. Newspaper inserts. With these I ask my neighbours who dont coupon to save me theirs as well I go to my local corner store the day after and ask for the inserts.
2. Check online resources. There are several websites that offer great coupons. They then mail the coupons to you:
3. Sign up for alerts with GroceryAlerts.ca a site that lets you know when new coupons are available.
4. Participate in forums on Frugal Shopper.ca, RedFlagDeals.com and SmartCanucks.ca. By participating in these forums I have access to the latest information shared by great couponers. I have also been able to trade coupons and even participate in coupon trains.
5. You can sign up for email or write directly from companies as well. Also sometimes you can get high value coupons by simply writing the companies you love. Most have a contact us page, try you using it.
Now that you have your coupons it is time to discuss how to use them:
Best way to use coupons in Canada
1. Use your weekly flyers to figure out what you want to buy that is on sale.
2. Match your coupons to what is on sale.
3. Compile your your shopping list and place coupons in an order so they are ready to use.
4. Check your store couponing policy. Different stores have different rules. Know yours. London Drugs is the only Canadian store that allows stacking. Stacking means they will accept more then one type of coupon for a product as long as they come from different media source ( ie. newspaper, inserts, online, etc. ).
Now the fun part. Shop and save. I have known many Canadians who have been able to cut there grocery bills in half simply by couponing.
