You can't build a bundle with Get Famous until after the Black Friday sale is over. A bunch of people were having problems with it, and Ea Mai responded with this in another thread:

Hi everyone,
As some of you have read on my Answers HQ post, The Sims 4 Get Famous Expansion Pack has been temporarily removed from The Sims 4 Build Your Bundle during the Black Friday Sale. It will be back November 27.
It seems some of you are still seeing The Sims 4 Get Famous on Build Your Bundle because of the browser's cache and this is of course causings some confusion. It's the same reason you will notice the price change when you go to the purchase confirmation page, as the pack is not meant to be available right now. Clearing your cache or using your browser's incognito mode should load the full and updated Build Your Bundle page.
If you would want to know more, I've posted a detailed (and a bit long) explanation here: https://answers.ea.com/t5/Technical-Issues-PC/The-Sims-4-Get-Famous-not-showing-in-Build-and-buy-a-bundle/m-p/7191287#M128351
Thanks!
