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

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 reservationsportal.
