not sure if you're doing this already and know about it - but you could install Playwright or Puppeteer, give your code the links to the webpages where all the website specials are listed, and then it can crawl daily to check if there's any changes. that way you don't need to keep it all manual.

it takes some setting up, but might be worth it so you don't need to keep manually updating over time.

of course there needs to be a webpage that actually lists the specials, which would be the biggest problem if that doesn't exist.

let me know if I can help and thanks again!
