You might try looking on popular online marketplaces like Amazon or eBay. They often have a wide range of manga sets available.
Check out specialized comic book stores. Some of them might have the Code Geass manga box set in English. Also, you could search on the official websites of manga publishers to see if they have it in stock or where it's available for purchase.
I'd suggest visiting local bookstores, especially those that have a large collection of manga. Sometimes, they have English versions of popular series like Code Geass. Another option is to look for it on manga subscription services that offer box sets.
