Field notes
Visitors can browse sale entries by category or search by product name or number; individual entries show the newsletter price, discount, and eligible dates when those details are available. The page separates warehouse-club offers from online listings and marks gaps, including items with no listed sale price or start date. A separate product memo lists 48 items checked against Costco’s online pages on October 26, while explicitly leaving current stock and prices unverified.
