Coupon

A coupon is an one-time random code, which is often used as discount code in digital or printed form. A user can apply the code by enter it in the order process to get the specified discount (see detailed description below).

Each code has it's own start time and end time (expiration time). A user can only apply a code in this time interval.

To create a coupon, you have to create a coupon group at first location, which contains codes with same settings (name, amount, etc.). Then you can add codes to the group. There's an export function allowing you to export multiple codes to CSV table.

Please protect the codes carefully to avoid any illegal usage .

Detailed Application Rules

Each coupon has four core parameters: service, discount rate, minimal discount, and maximal discount.

When submitting an order, the system calculates the total price of all articles belonging to the specified service as the base.

Then the discount rate of base will be reduced. For example when a coupon with 10% rate of an order of $10 is applied, the discount will be 10% x $10 = $1, the final amount will be (1 - 10%) x $10 = $9.

If the discount is less than minimal discount, the coupon is still applied but the discount is set to $0. In the above example, if the minimal discount is set to $2, then the final amount will be $10.

If the discount is more than maximal discount, the coupon is still applied but the discount is limit so that the discount is not larger than the specified value. In the above example if the maximal discount is set to $0.5 and minimal discount is unset (or set to $0), then the discount will be 5% x $10 = $0.5 and the final amount will be (1 - 5%) x $10 = $9.5, or calculate in this way $10 - $0.5 = $9.5 since the original discount $1 is larger than $0.5.

It's notable that all the discount is calculated after the tax if the tax is specified.

Voucher

A voucher is an one-time random code, which is often used as gift card in digital or printed form. A user can apply the code by entering it in their user center to get the specified amount of money assigned to their balance. The balance can be used later to pay the order fully or partially.

Each code has it's own start time and end time (expiration time). A user can only apply a code in this time interval.

To create a voucher, you have to create a voucher group at first, which contains codes with same settings (name, amount, etc.). Then you can add codes to the group. There's an export function allowing you to export multiple codes to CSV table.
