A coupon changes both the offer and its economics. Define the behavior to test, such as a first order, stock clearance or a returning customer, then assess costs after discount, delivery and fees. Higher sales do not automatically mean healthier orders.
Choose a measurable objective
Specify audience, products, period and eligibility. A public code differs from an offer limited to a category or minimum basket. Use restrictions the system actually supports instead of advertising unenforceable conditions.
Review exclusions, limits and stacking with other promotions. Test eligible and ineligible carts and explain why a code cannot apply instead of showing a generic error.
Calculate the effect using a transparent example
The following is a simplified hypothetical example, not Mollkom pricing or actual store performance. Assume a SAR 100 order before discount, SAR 45 merchandise cost, SAR 5 processing and SAR 10 merchant-funded delivery. Contribution is SAR 40 before ads, fixed costs, returns and taxes.
A SAR 10 coupon reduces that contribution to SAR 30 if the assumed costs stay unchanged. Maintaining the same order count therefore does not offset the discount. Recalculate using actual fees, applicable tax treatment and provider terms.

| Item | Before coupon | After SAR 10 coupon |
|---|---|---|
| Customer amount | 100 | 90 |
| Merchandise cost | 45 | 45 |
| Assumed processing | 5 | 5 |
| Assumed delivery | 10 | 10 |
| Contribution before other costs | 40 | 30 |
Test cart, shipping and refund behavior
Check how the configured flow applies discounts, shipping and minimum basket value. Remove an item after applying a code, change quantities and inspect the final total.
Verify cancellation and partial-return treatment and ensure reporting does not subtract a coupon twice. Review the actual system behavior rather than assuming every discount type is calculated identically.
Evaluate incremental value, not code usage alone
A customer may use a coupon for a purchase they would have made anyway. Review new customers, repeat behavior, delivered orders and contribution after costs, using a suitable comparison where possible.
Set a test limit and do not extend an offer solely because many codes were redeemed. Mollkom’s connected products, marketing and order context can support review, but economic results depend on the business’s actual data.
Common questions
Does high redemption mean success?
Not alone. Review delivered orders, contribution, incremental customers and purchases that may have happened without the discount.
Should I use this example to set my discount?
No. It illustrates the calculation. Use actual costs, objectives and system terms to make the decision.
Your next step
Continue with marketing connected to operations, or register and start your store. Apply the process to a small sample before expanding.
