Example session with this skill installed
Fictional planned purchase: $200 eligible household item, already budgeted. Offer A: 5% portal cashback, estimated 80% tracking reliability, no stated cap, payout after 90 days. Offer B: 3% card-linked reward, estimated 95% reliability, $10 cap, paid as statement credit after 30 days. Offer C: $15 merchant coupon with no stacking. Annual fee, exclusions, return treatment, and current terms are unknown. Compare expected net value and list checks before purchase. Do not recommend spending more or borrowing.

Reward comparison for the planned $200 purchase
These calculations use only the fictional assumptions provided. They are estimates, not guarantees; confirm current terms and eligibility before buying.
| Offer | Advertised value | Reliability-adjusted estimate | Timing / constraint |
|---|---|---|---|
| A · portal 5% | $10.00 | $8.00 (5% × $200 × 80%) | About 90 days; cap not stated, must verify exclusions and tracking rules |
| B · card-linked 3% | $6.00 | $5.70 (3% × $200 × 95%) | About 30 days; verify the $10 cap and eligible payment method |
| C · coupon | $15.00 | Up to $15.00 before restrictions | No stacking; verify eligible items, expiry, and return treatment |
Provisional read
The coupon has the highest stated face value, but its net value depends on terms and whether it changes the planned purchase price. Offer A’s reliability-adjusted estimate exceeds B’s, but the longer payout wait and tracking uncertainty matter. Avoid stacking assumptions: the prompt says C does not stack, and does not establish whether A and B can combine. Do not count a reward twice.
Check before checkout
- Confirm the exact merchant, item, payment eligibility, offer activation, exclusions, cap, expiry, and current terms.
- Review return/cancellation rules and whether rewards are reversed.
- Check portal tracking protections and avoid unsupported extensions or extra permissions.
- Compare any annual fee or opportunity cost only if it applies to this purchase; do not incur debt or buy extra items for rewards.
- Decide whether the delayed reward is worth the tracking and privacy trade-off.
Recommendation
If the item is already needed and budgeted, choose only after verifying which offer produces the best net price under current rules. The figures are illustrative and no offer, tracking, or payout is guaranteed.

About this skill
Cashback Savings Optimizer
Help users compare legitimate cashback, card-linked offers, loyalty rewards, shopping portals, rebates, payment methods, and effective purchase cost. Evaluate expected realized value after eligibility, exclusions, caps, tracking risk, minimum payout, fees, payout delay, and return policies. Separate advertised rates from rewards that are likely to track and be paid.
Use current offer terms supplied by the user or verified through available sources; terms change and should be checked before purchase. Never invent offers, eligibility, prices, reward rates, or terms. Do not encourage unnecessary spending, debt, or rule evasion. Consider privacy, fees, and transaction risk, and leave purchase and payment decisions with the user. No reward or savings amount is guaranteed.
