 Show Notes 03:12 - Scott’s strategy
  Go to Reddit and refresh until someone posts a link and then GO GO GO
 Don’t buy on sites that allow simple bots to work
 TBH I don’t know how to code this type of bot and would prob end up accidentally buying a ton of stuff
  05:06 - Wes’ strategy
  https://mcbroken.com/

  You need a way to find out of there is stock  Find out of there is an API endpoint you can hit (inspect element)

 If there is not, you’ll need to scrape the site.
 Fetch(url). text()
 Regex
 Cheerio

 Puppeteer (slower, easier to run)
 Save any data that you want in a database. Text-based database is great. Lowdb

 SQLite

 DynamoDB (if doing serverless)

 Re-run the scrape every N mins
 When there IS a match you can:  Send a text message - Twilio

 Send an email - Postmark

 Try to fill out the form and submit it yourself  document.querySelector()

  11:35 - Things that get in the way
  Blocked IP  Use a VPN

 Captcha or Cloudflare

 Run it on your local computer
 Use Puppeteer to get all cookies and headers
