On some big events such as Black Friday, Valentine's Day,... Oxygen will constantly offer up to 50% discount or more, so all customers can purchase well on their budget without worry.

In case you enter a discount code during checkout that doesn't exist or isn't currently active, then you can see the message: “Unable to find a valid discount matching the code entered”.

Normally, one discount code is only applied for one offer. However, If the users put a vast of items in their cart, it is easy to use one coupon code to purchase items. It depends on Oxygen's policy, you can contact Oxygen via mail for your reference.

Firstly, you need to check out whether Oxygen offers Oxygen 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 Oxygen profile and start searching for Oxygen First Time Coupon.

There is no certain number for the frequency of releasing coupons from Oxygen. But, most of the time, there will be at least one available. Special Discount Days such as Black Friday, Cyber Monday, Back to School Sale... come with many coupons.
