Stacking coupons is a pretty easy to understand concept.  When you stack your coupons, you  combine the value  of your coupons with other coupons or discounts, in order to boost your overall savings.

Stack your coupon with an in-store sale. For this technique, you need to browse through your store’s weekly advertisement, to see what products they have on sale.   While you look through the ad, have your coupons handy, to see if you have coupons for the items that are on sale.    For example, if your grocery store has Honey Bunches of Oats cereal on sale $2 per box, and you have some coupons that are $1 off each box, you’ll pay only $1 per box.

Stack your coupon by shopping on double- or triple-coupon days. If you’re lucky enough to live in an area where stores multiply the face value of a coupon, by all means, take advantage of it!

Stack your coupon with a rebate. Sometimes, manufacturers will offer money-back rebates on some of their products.  An example of this would be if Schick is offereing a $5 rebate on their new $6 razors, and you have a $2 off coupon.  For your purchase, you could use your $2 off coupon for your $6 purchase.  You’d then use your rebate form and receipt to send to the company for your $5 rebate.  In the end, you will have made a profit of $1 for buying that razor.

Stack your coupon with another coupon. Yes, you can use more than one coupon per transaction in certain circumstances.  The general rule in using coupons is that the buyer is limited to one coupon per UPC code.  Take for example, a coupon that is an offer for “buy one get one free.”  In this case, if you have two coupons that both say “buy one, get one free,” and you purchase the required two products, they will both be free.   This technique can also be used if your store is running a “buy one, get one” in-store sale.
