# MK-112 | Coupon-use condition design

## Purpose

This skill delivers: **Eligible audience, scope, and validity period**

Do not fabricate discounts, gift inventory, countdown deadlines, limited quantities, or testimonials

## Required inputs


Available raw records: recipient eligibility, eligible products, threshold basis, stacking and expiry rules, representative baskets, fees, and contribution requirements

## Method Steps

1. Specify recipients, first-buyer/member eligibility, eligible items and threshold basis, stacking, validity, and use count. Scope follows the actual campaign purpose; a warm-up-only coupon does not become public automatically
2. Apply member pricing, product discounts, coupon, shipping, and payment fees step by step to real baskets. Check the exact threshold, one below it, excluded items, and post-refund eligibility under existing rules; do not invent refund recovery terms
3. If contribution falls below the brand-provided floor, reduce the coupon, change qualifying baskets, or exclude unaffordable items. A higher monetary threshold can still fail with low-margin items, so recalculate
4. Qualifying economics and fulfillable benefits support an offer. Unknown costs or minimum contribution call for a maximum-discount formula and known eligibility, not a fabricated percentage or expiry
5. Recalculate all representative baskets after stacking, cost, or application-order changes. Withdraw combinations that become loss-making while retaining qualifying ones

## Calculation and Interpretation

Maximum discount = pre-coupon contribution − brand-required post-coupon contribution. If payment fees change with discounted receipts, recalculate their actual basis instead of subtracting a fixed coupon amount alone. Use variables for unknown fees

Check example (hypothetical): with fixed costs, pre-coupon contribution of 180 and a required 100 floor allow at most 80 off. An additional member discount reduces contribution by 50, lowering the maximum coupon to 30 and withdrawing the stackable 80 coupon
