Discount codes don't stack. If you have 56% 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 Netvue 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 Netvue's policy, you can contact Netvue via mail for your reference.

Our advice for you to use Netvue Coupon effectively is to choose the right day.
Like thousands of other consumers, the time of promotion is when they choose to
shop at Netvue, so take advantage of coupons released on those days to save.

Shoppers can get coupons for their first purchase at the store. However, it is not all the time, sometimes, they cannot apply a discount on items selling out or items not contained in the promotion program. It depends on the time you shop at Netvue.

The sitewide discount from Netvue is applied on certain purchases. For Year-End Deals, the store may have its own requirement to offer you a sitewide discount.
