The catalogue, still in beta and being added to, contains a listing of house-items by type. Clicking through to a category, and then an individual item, will bring up a picture of said item, a short description, the cost, and exactly where to get a hold of it. Very handy! The items can also be selected directly from a drop-down menu.
As more things will undoubtedly be added in the future, the site may be worth a bookmark if you feel you may have an ongoing affair with decking out your place. After all, the next time your neighbours visit to smoke some pipe-weed, you want them leaving jealous, don't you?
