The lowes coupon codes are a great way to get a discount on the purchases you make from Lowes. The coupons are available online at several coupon sites, and each coupon has a unique code that you need to enter in the store. The store associate, who will then swipe your card, will then enter the code into the cash register and apply the discount. The coupon site will also allow you to print the coupons as hard copies and use them to enter the code at the store. This way, you avoid risking your card to skimming, and you can also avoid losing your hard copy coupons if you are on the go!
