Grocery Check

Expiry algorithm (Quebec flyers run Thu→Wed):

from datetime import datetime, timedelta
today = datetime.now()
days_until_wed = (2 - today.weekday()) % 7
if days_until_wed == 0:
    days_until_wed = 7  # today is Wed — expires end of tonight
expires = (today + timedelta(days=days_until_wed)).replace(hour=23, minute=59, second=59)

Scraping Workflow

For each store in preferred_stores, navigate and extract using the store-specific pattern below. Always wait 5 seconds after navigation for JS to render.

Metro

URL: https://www.metro.ca/fr/epicerie-en-ligne/circulaire?sortOrder=relevance&filter=%3Arelevance%3Aoption%3Asuggestion-for-you

1. browser_navigate → URL
2. If cookie consent dialog appears → click "Accept All"
3. browser_wait_for (time: 5)
4. browser_snapshot → extract deals

Pattern in snapshot:
  link "PRODUCT NAME" → /url: /fr/epicerie-en-ligne/allees/...
    → Prix régulier → text: REGULAR_PRICE
    → generic: SALE_PRICE

Discount = (1 - sale/regular) × 100

Super C

URL: https://www.superc.ca/fr/epicerie-en-ligne/circulaire?sortOrder=relevance&filter=%3Arelevance%3Aoption%3Asuggestion-for-you

1. browser_navigate → URL
2. browser_wait_for (time: 5)
3. browser_snapshot → extract deals

Pattern in snapshot:
  link "PRODUCT NAME SIZE" → /url: /allees/...   ← note: /allees/ not /fr/epicerie-en-ligne/allees/
    → Prix régulier → text: REGULAR_PRICE
    → generic: SALE_PRICE

Maxi

URL: https://www.maxi.ca/fr/deals/flyer

1. browser_navigate → URL
2. browser_wait_for (time: 5)
3. Dismiss location/store dialog if present
4. browser_snapshot → extract deals

Pattern in snapshot (English labels):
  generic: "sale" → text: $SALE_PRICE
  generic: "was"  → text: $WAS_PRICE
  paragraph: BRAND_NAME
  heading (level=3): PRODUCT_NAME

Note: lazy-loads ~20 items on first view. Accept partial results or scroll for more.

IGA — grid view has real sale prices

URL: https://www.iga.net/fr/circulaire?view=list
(or navigate to /fr/circulaire, dismiss tour, click second tab)

1. browser_navigate → https://www.iga.net/fr/circulaire?view=list
2. browser_wait_for (time: 4)
3. Accept cookies if dialog appears ("Tout accepter")
4. Dismiss tour modal if present ("Sauter" / "Fermer")
5. browser_snapshot → extract deals

Two item types in grid:

a) SALE items — identified by ÉCONOMISEZ marker:
   Pattern: generic: SALE_PRICE $ → generic: WAS_PRICE $ → ÉCONOMISEZ → generic: SAVINGS $
   Extract sale price, compute % = (1 - sale/was) × 100

b) Scene+ bonus items — identified by +TPS +TVQ after price:
   Pattern: generic: PRICE $ → paragraph: +TPS +TVQ → Achetez N et obtenez X PTS
   Extract: product + price + bonus points offer

Note: page lazy-loads ~20 items. Scroll or accept partial results.
In output, separate real discounts (ÉCONOMISEZ) from Scene+ bonus items.

Stores without text-extractable flyers

If a store isn't listed above, skip it and note: "flyer not text-accessible for [store]".

Extraction Rules

• Food items only: protein, produce, dairy, pantry staples — skip cleaning products, personal care, beer/wine unless in preferred_stores config
• Flag exceptional deals: >40% off shown prominently
• IGA: distinguish ÉCONOMISEZ (real discount) from Scene+ bonus items (regular price + points)
• Failures: if a store fails or returns no deals, skip and note — don't block the run
