Costco.ca's terms of use forbid bots and the collection of its listed prices, so we don't scrape it. Items are entered from the printed or in-warehouse coupon book (photo → OCR → human check).
Unlocks when: the editor adds this week's coupon-book entries (data/manual/entries.csv) and a human approves them.

How we check Costco prices
- An editor photographs the coupon book or in-warehouse sale signs.
- OCR reads the item number, sale price, regular price and dates; a fact-checker compares each line with the photo.
- Our database flags items that are cheaper than any previous sale we recorded.
