Discount codes don't stack. If you have 53% off discount, they can't also use a "free shipping" coupon since Only one discount at a time can apply to a single order at the Nebula site.

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 Nebula's policy, you can contact Nebula via mail for your reference.

Normally, most of the websites you can print the grocery coupons from only work on a computer, even you can get coupon books mailed to your home for free. But it completely depends on Nebula's support program at the time you search, so please visit the Nebula site to know more details.

At the time of updating, Nebula has not applied Student Discount all year round yet. Check the official store and reach out to the customer support team to be clear.
