So let's start with what coupon stacking is: Using more then one coupon on an item.
Normally, in any other store, you can only use one coupon per item. This means one coupon for each product. So if you buy 4 boxes of crackers, you can use 4 coupons. At London Drugs, you can use more then one coupon on each product.
For example: I have 2 coupons for Garnier Fructis Haircare. One is $1 off one bottle and the other is $1 off one bottle. They are both tear pad coupons found in drugstores. They have different UPC's on the back. As long as the UPC numbers are different, they are considered to be different coupons. If the UPC numbers are the same, but the coupons look different, you cannot stack them. They are considered to be the same coupon.
I can buy one bottle of Fructis shampoo and use both coupons and save $2.
These Tylenol Arthritis coupons look different. One is from a coupon insert and one is a tear pad. But, they both have the same UPC numbers, so I CANNOT stack these. If they had different UPC numbers, I could use both on one bottle and get $6 off.
Now of course, you also need to consider the wording on the coupon. Although some companies put out multiple coupons for the same product and they have different UPC's, the wording on the coupon restricts London Drugs from allowing stacking on them.
A good example of this is P&G or Proctor and Gamble. On their coupons it is very clear, no stacking allowed. It says,
"use of more then one manufacturer coupon per product is strictly prohibited"
The following list is something I printed and kept with my coupons for a while, until I knew which ones I could stack. This is the exact same list that my London Drugs keeps at the till:
1. "Not valid with any other coupon offer" Not Stackable
2. "Use of more than one manufacturer's coupon per product is strictly prohibited" Not Stackable
3. "Limit 1 coupon per purchase". STACKABLE
4. Not valid in conjunction with any other coupon" Not Stackable
5. "Cannot be used or combined with any other coupon offer" Not Stackable
6. "Coupons/ Offer not valid in conjunction with other offers, promotions, or discounts" & can’t be used with sale items. STACKABLE
7. "One coupon per purchase" STACKABLE
8. "Not valid with other offers" STACKABLE
9. "One redemption per customer" This means one of this type of coupon per customer, STACKABLE
10. "One coupon per purchase, One redemption per customer" STACKABLE but you can only buy one with a coupon
Now, let's say you have two coupons for $4 off 2 bottles of Children's Tylenol and $1 off 1 box of Children's Tylenol. You can use all 3 coupons. (as long as the UPC numbers are different)
You use 2 coupons of $4 each on 2 boxes and one coupon of $1 on one box - for a total of $9 off 2 boxes.
Examples of products that have restrictive wording and CANNOT be stacked at London Drugs:
- Glade, Arm & Hammer, Scrubbing Bubbles, Tide, Air Wick, Pantene, Head & Shoulders, Secret, Old Spice, Melitta, Charmin, Bounty, Crest, Always, Cover Girl, Oral B
Examples of products that I stack at London Drugs:
- Aveeno, Dove, Tresemme, L'oreal, Tylenol, Motrin, Advil, Benadryl, Greenworks, K-Cups, Kelloggs, Carnation, Degree, Stayfree/OB, Vaseline, Axe, Schick, Buckley's, Fructis, Alberto, Bic, Speedstick, Barilla, St. Ives, Centrum, Johnson & Johnson.
It's also not difficult to make money by stacking at London Drugs. Let's say that Degree Deodrant is on sale for $1.99, I have 2 different coupons worth $1 each. I get the Degree for free, plus there is a $1 rebate on Checkout 51 for $1 on Degree. I submit my receipt after I bought it, and I now made $1 for buying Degree.
Now let's say a product is $3.50 and you have 4 different $1 coupons with different UPC's. At the till, the cashier will reduce the value of your 4th coupon to .50 cents, so that you don't go over the price of the product.
The best use of your coupons is to use with them with a sale. London Drugs will price match local stores from a paper flyer or your phone or tablet. I use apps like Reebee or Flyerify. When you are price matching and then stacking coupons, there is a limit of 4 products of each type.
Stacking coupons takes more time at the till, so always go to Customer Service and let the cashier know that you are stacking so that they can get the appropriate cashier to help you.
You are not permitted to stack during peak hours. It holds up other customers. I usually go in after 7 pm or when it's quiet during the day. Your store may have specific hours for stackers.
It's a good idea to be organized and have your coupons paper clipped together for each product that your buying. I also double check my coupons at the shelf to make sure the wording is correct with the product I am buying. Check sizes, types etc. to make your checkout go smoothly.
I also use the London Drugs website to check prices before I go in. This way I can have my stacks ready to go. They have a search button to look up the products, the current prices are listed with each item and they also have all their flyers on the site.
At the till, I put each product on the counter with the appropriate coupons so that the cashier can check the coupons against the product before they ring it in.
While this is a lot of work initially to learn, this skill has saved me hundreds of dollars a year. Items that I rarely pay for like hair products, toiletries, laundry soap, cleaning products, and over the counter medications, are items that can double your grocery budget every month.
I take the savings in this area and re-direct it to grocery purchases that don't have coupons like fresh produce, meat and dairy.
