Our marketing wants to send vouchers to customers.

The best fit discount type for vouchers is "Spend for Discount on Order".

So there are blockers with this discount type:

1. It is designed with exclusions in focus, which is a bad idea.

We sell tyres & wheels, and plan to send voucher on a wheel alignment.

With the given  design we will have to exclude all products except one.

There has to be a switch, so we can either put inclusions or exclusions for "Spend for Discount on Order".

2. With the given design we are forced to create a discount for each individual voucher.

In result we end up with a promo which consists of several thousands "Spend for Discount on Order" discount lines, each having individual products exlusions.

Is it impossible to create this promotion from EPI UI (how would you setup 1000 voucher product exclusions?)

It is the only way we can apply individual voucher to a cart and track redemptions.
