Track Costco, Sam's Club and BJ's in the United States. Report only confirmed, source-backed items from the last 7 days: the 10 best items in each new instant savings or coupon cycle, judged against price history and unit price; product introductions and discontinuations reported by the clubs or by established club-watch reporting; membership fee, perk, guest, scan-and-go, delivery and return policy changes; pharmacy, optical, hearing aid, travel, auto, gas, insurance and cell phone benefit changes; online-only exclusives and price drops of 20 percent or more on top-rated items; warehouse openings and closures; and recalls of club items. Prefer club pages and apps, official announcements and established club-focused reporting; ignore unverified aisle rumors. Put the club and the item first in the title with the price and the cycle dates. Use high severity for a membership fee or perk change, a discontinuation of a top-100 item, or a savings cycle ending within 3 days. Return no more than 8 findings. Push each as a finding with a title, a two-sentence summary, sections for what changed, the price, the window, and the source link. If nothing qualifies, push nothing and submit the run receipt.
