Quick-Fix Checklist
- Update PC Optimum app to the latest version.
- Turn phone screen brightness to 100 %.
- Disable dark-mode or blue-light filters.
- Remove thick screen protector or rotate phone landscape.
- Toggle store Wi-Fi off if signal is weak; rely on data.
- Double-check product size/SKU matches coupon wording.
- Verify expiry—coupons end 11:59 PM ET regardless of local time.
- Ask cashier to key “021” + code if scanner still fails.
Why it happens: Laser scanners struggle with low brightness, thick screen protectors, or glare from overhead lighting. The store’s older Motorola scanners need a crisp, high-contrast barcode.
- Turn brightness to maximum and disable dark-mode.
- Remove any matte/glare screen protector or rotate phone 90°.
- Hold phone 10 cm back so the red laser can focus.
- Tap the barcode area once—most phones hide the navigation bar, enlarging the code.
- If still failing, ask cashier to press 021, key in the full 20-digit code, then hit ENTER.

Why it happens: Limited-quantity offers auto-expire once redemption quotas are hit. Occasionally the app drops cached offers after an update or time-zone switch.
- Pull down to refresh the “Offers” tab.
- Force-quit and reopen the app, then check again.
- Toggle airplane mode on/off to flush stale cache.
- If the offer is flyer-based, scan the product at self-serve price checker—sometimes the register still recognises the code.
Why it happens: Multi-use coupons register each barcode scan on the PC Optimum backend. If Wi-Fi dropped mid-transaction the system flags a redemption attempt even when transaction voids.
- Ask cashier to void last line and re-scan.
- If message persists, remove the coupon item from basket and pay separately.
- Still stuck? Scan loyalty card after the barcode so system sees fresh token.
Why it happens: Corrupted cache or an outdated version conflicts with Android/iOS webview components.
- Update PC Optimum in the App Store/Play Store.
- Clear cache (Settings → Apps → PC Optimum → Storage → Clear Cache).
- Restart phone. Preload coupon while waiting in line so barcode is cached offline.
Why it happens: PC Optimum matches offers by 12-digit SKU. New seasonal packaging or bonus-size may share shelf tag but not the original SKU.
- Scan product with price-checker kiosk; SKU appears bottom-left—compare to app fine print.
- Select original size/flavour shown in offer image.
- Avoid trial sizes; they’re usually excluded.
Why it happens: Shoppers allows one PC Optimum coupon per product line. Scanning two different barcodes for same item family triggers conflict.
- Use second coupon on a separate transaction or different product flavour.
- Combine a digital coupon with a paper manufacturer coupon instead—review the Shoppers Drug Mart coupon policy.
Why it happens: Network latency during peak hours delays points post. System batches may take up to 24 h.
- Wait 24 h and refresh account.
- If still missing, use in-app chat > “Points Inquiry” > upload receipt photo.
- Provide store #, transaction #, and exact points expected.
One-Minute Diagnostic Flow
- Does the coupon appear in the “Offers” tab?
- Is your app up to date?
- Brightness at 100 % and screen protector off?
- Barcode still not scanning → ask cashier to key 021 + code.
- Gets “already redeemed” → void line, re-scan loyalty card.
- Offer missing points after 24 h → start in-app chat.
- No resolution within 5 days → escalate to PC Optimum call centre.
