Since your account is under three months, you're only able to restock r94 items for now.
Once you've reached three months, everything is "available." You can access the attic once your account reaches 36 months. There's an attic buyer in the download section. You can see it (you need an account to see links), but you either have to be a Top clraik, or VIP. There's an autobuyer for shops in the downloads section (you need an account to see links). As for a list, you'll have to specify which shop you want to AB in/at. There's also an autobuyer lists thread here, click (you need an account to see links) to view it.
