There are so many websites are providing shopping coupons in two ways. Those are ” printable coupons” and “coupon codes”. But we have to check those coupons i.e whether it is working or not before check out. You may check the validity first. we will find the expiry date in coupon details only.
You may print a coupon from an unknown source , you may check the validity. For this some of the sites will give a text box for verify the coupon code. Every Coupon has its unique code. If you have two coupons with the same code – one or both are fraud.
