Coupon Stack Optimizer — Find Better Legitimate Discount
Example session with this skill installed
Illustrative scenario: Compare supplied offers on an $100 eligible cart, with tax excluded for this exercise. Shipping is $8 unless post-discount merchandise is at least $90. Code A gives 20% off; Code B gives $15 off; they cannot combine. A supplied cashback offer allows either code and gives 5% of post-discount merchandise, excluding shipping, but payment is not guaranteed. No membership fees. Give immediate cost, cashback scenario and recommendation. Do not browse or purchase.

Offer rules and baseline
Supplied terms only; no live checkout verification. Codes A and B are mutually exclusive. Cashback permits either code under the supplied offer. Shipping uses the post-discount merchandise amount. Tax is intentionally excluded for this exercise, not assumed zero in a real purchase.
Without a code: $100 merchandise qualifies for free shipping, so immediate baseline is $100.
| Option | Discounted merchandise | Shipping | Immediate payable | Conditional cashback | Effective cost if paid |
|---|---|---|---|---|---|
| A: 20% off | $100 × 80% = $80 | $8; below $90 | $88 | $80 × 5% = $4 | $84 |
| B: $15 off | $85 | $8; below $90 | $93 | $85 × 5% = $4.25 | $88.75 |
| No code | $100 | $0 | $100 | Not modeled; applicability not specified for this comparison | $100 baseline |
Recommendation
A is the lowest immediate-cost option among the supplied code choices: $88, saving $12 against the $100 baseline after shipping. If the $4 cashback is eventually paid, its scenario effective cost is $84. Treat that reward as pending, not an immediate checkout deduction. B costs $5 more at checkout and $4.75 more after the modeled rewards.
Reliability and boundaries
No probability of cashback receipt is supplied, so no risk-adjusted expected reward is invented. A remains the preferred immediate-cost choice even if cashback fails. Do not combine A and B or create another account to evade redemption limits. Do not add unwanted merchandise merely to reach a threshold without comparing its full incremental cost.
Checkout checklist
Confirm cart eligibility, code validity/expiry, discount base, shipping threshold, tax, exclusions, redemption limits and cashback tracking requirements. Verify the accepted code and final total before any purchase. Record order evidence only with authorization; keep payment details private.
No code was applied, account accessed, purchase made or cashback received. These are calculations from an illustrative supplied offer set.

About this skill
Coupon Stack Optimizer helps shoppers and procurement teams compare lawful, policy-compliant combinations of coupons, promotions, loyalty, cashback, rebates, gift cards, payment offers and shipping benefits. Its goal is the lowest defensible payable or effective net cost rather than the biggest headline discount.
The workflow checks supplied or verified terms, eligibility, exclusions, expiry, minimum spend, redemption limits, order of operations and stackability. It separates immediate checkout savings from delayed rewards, models conflicts and fees, and compares reliable, simple and repeatable options against a transparent baseline.
Browsing, cart access, files and calculation tools depend on actual host capabilities and authorization. Without current access it works from supplied terms and marks acceptance pending. It does not invent codes, rates or eligibility, recommend rule circumvention or guarantee coupon acceptance, cashback tracking or future availability. Purchases and account/payment actions require separate authorization.
