It is possible to find legitimate 20 percent off coupon codes online, though availability depends on the store and the source of the coupon codes. Some coupon codes are available for 25 percent off or more for some retailers, notes ABC News.
For example, users might find legitimate 20 percent off coupon codes directly on the website of the retailer. As of September 2015, JCPenney offers such codes on specific products, though sometimes users need to use a certain payment method to get 20 percent off or more. Coupon websites like DealsPlus and CouponCabin group deals by retailer and can also include codes for 20 percent off or more.
Checking both the retailer's website and coupon sites, as well as using search engines to find codes for 20 percent off coupons, are recommended methods, according to ABC News.
