But I can't find what I'm looking for!
So, you're bought a lovely house and you're looking for juuuust the right bit to fill it. If you're on a console, you'll have to search and search through the guild stores looking for that perfect recipe or furnishing, but if you're on PC, you're in luck!
Check out the Tamriel Trade Centre website and search for exactly what you're looking for!
I've used this multiple times to find exactly the pattern I'm looking for, and it's sort-able by time last seen or price, which is particularly helpful.
And it's not just for furniture of course; you can search for any items that can be found in a guild store.
You can help out by installing the companion mod which will upload what it sees in a guild store to the database.
