You may have come across the Link Builder in a free Epic Games post. It started as a utility to make things easier me to add all the weeks free games to all the family accounts without having to go through each title one by one, and easily unselect any that were already in the library and cause checkout to fail.
I guess the next step would be to get it automated but for now I manually update the titles and thought there must be an easier way to get the ids etc for checkout links.
So after fighting the AI bot to get what I want, then giving up and doing a bit of manual editing I think I have a pretty functional bookmarklet that should make things easier for me and the deal posters too.
Add the bookmarklet to your bookmarks toolbar, visit any Epic game store page and in a click it'll instantly spit out the purchase link for that title. Even has handy clipboard buttons for the purchase URL, the CSV for my builder page, and even the markdown to paste the title and links in a deal description. Probably useful to about 3 people but thought I'd share anyway :)
(PS, i did have the odd instance where it was pulling up the wrong title, turned out to be a caching issue. Refreshing the page and clicking again sorted that.)
(Updated to check if the data is stale so it will prompt you to reload)

Link Builder page is now fully automated and should have the current weeks titles as soon as they become available. Let me know if you see anything strange there next Friday :)
