To use the KOS coupons on their website, you need to meet the conditions:

•  The items you choose must meet all coupon requirements as explained in the Terms and Conditions.

• The coupon has not expired. 

• The seller uses the KOS checkout system or a customized checkout system that accepts the coupon.

Please check out KOS's site to be sure that there are available KOS coupons for promotions or Customer Service at that time. In case you are chosen to obtain those available coupons, you may receive your coupon by email, or a mailed catalog or postcard.

Firstly, you need to check out whether KOS offers KOS First Time Coupon Programs at that moment or not. If this program exists you can:

• Step 1: Sign up for a new Gmail, Yahoo, or whatever other email service provider that you want.

• Step 2: Complete your new KOS profile and start searching for KOS First Time Coupon.

Most Big Discount Events of the year witnessed a vast number of coupons from KOS released. Especially, on federal holidays such as New Year’s Sale, Thanksgiving, Christmas... or on other important days such as Valentine’s Day, Easter, and Father’s Day..., customers also can buy at KOS with numerous coupons.

There are now 17S offers on our site and KOS Coupon Codes usually end in 3-4 days. However, some KOS Deals don't have a definite end date, so it's possible that the code will be working until the store runs out of inventory for the promotional item.
