About this skill
Problem
Users often have coupons across platforms: 300-50, 20-8, store coupons, and cross-store red packets. These may differ in threshold, expiry, category limits, and stacking rules. Manual comparison can miss deadlines or cause purchases just to meet a coupon threshold.
How It Works
The skill does not read apps or redeem coupons. It works from user-provided fields: platform, face value, threshold, expiry, scope, and planned purchases. It ranks coupons by expiry, calculates discount rate = benefit / actual spend, notes usage conditions, and compares whether using several coupons or one larger discount is better. For spend-threshold coupons, it checks whether padding the cart is worthwhile; if extra purchases exceed the discount, it flags the choice as poor value.
Limits
Use it for local coupon notes, checkout checks, and discount comparisons. It is not for auto-claiming, real-time price tracking, coupon trading, or fake-order coupon schemes. Platform rules can change, so the final checkout page remains authoritative. Do not share verification codes or payment credentials.
Use Cases
- Before checkout, rank multi-platform coupons by expiry and calculate the final price after stacking.
- Compare delivery red packets and store coupons, then choose the higher discount-rate option first.
- Check whether adding a 30-yuan item to reach a spend threshold saves more than it costs.
- Label category limits, expiry dates, and non-stackable rules from scattered coupon notes.
Best For
- Consumers who stock daily goods across platforms and need to decide which coupon to use first at checkout.
- Procurement assistants who must verify spend-threshold rules and non-stackable limits before team purchases.
- Personal budget trackers who want to turn scattered coupon records into an expiry-priority checklist.
- People ordering delivery for family and comparing red-packet discount rates to avoid over-padding carts.
