Why operations teams switch to Promotion Checker
Unintended discount stacking, excluded-SKU leaks or broken threshold rules are too often discovered by customers at checkout. Promotion Checker replaces fragile manual checks with a repeatable, human-approved workflow built around your catalog and finance rules.
02
Verify Brand & New-Drop Exclusions Automatically
Ensure full-price carry-over styles, gift cards and restricted collaboration SKUs neither receive discounts nor accidentally count toward spend thresholds.
03
Sign Off Campaigns With a Pass/Fail Matrix
Replace frantic midnight manual cart clicking with a repeatable verification checklist across currencies, customer tags and cart mixes.
THE OPERATIONAL SHIFT
Before vs. after Promotion Checker
Without Promotion Checker · Manual status quo
Where your team loses hours
- A 20% VIP code accidentally stacks on top of a 30% automatic BFCM tier, giving away 44% off for 3 hours.
- Excluded new-season boots still trigger the '$200 Free Gift' threshold because a collection tag was missed.
- Team members manually build 6 test carts in incognito tabs and miss multi-currency edge cases.
With Promotion Checker · Agreed workflow
How your workflow runs after onboarding
- Every discount code, automatic rule and bundle interaction is tested across a structured cart matrix.
- Mixed carts (eligible + excluded SKUs) are verified to confirm exact line-level discount behavior.
- Merchandising and finance get a clear Pass/Check verification table before the campaign goes live.
ILLUSTRATIVE SCENARIOS
Example edge cases for Promotion Checker
SCENARIO 01
BFCM Tiered Spend + Loyalty Code Stacking
The operational problem
A 'Spend $250 Save $50' automatic discount was configured with combinations enabled, allowing 15% referral codes to stack.
Example outcome with Promotion Checker
Cart C simulation flagged the combined discount interaction 3 days before launch, saving thousands in unintended margin give-away.
SCENARIO 02
Mixed Cart With Excluded Limited-Edition Drop
The operational problem
Adding an excluded $180 limited-edition sneaker alongside a $30 sock unlocked a 'Spend $200 Get 25% Off' promo across the cart.
Example outcome with Promotion Checker
Cart B boundary check exposed the qualifying-subtotal leak so the exclusion collection was properly scoped.
SCENARIO 03
Multi-Currency Threshold Drift
The operational problem
UK and EUR storefronts had fixed-amount thresholds that didn't align with converted product prices after a price-list update.
Example outcome with Promotion Checker
Verified exact threshold qualification across USD, GBP and EUR test carts prior to campaign announcement.
