If you have a 3 month account, you can see all items up to r99 anyway. Which means you can use every AB list. If your account is under 3 months, i'd suggest using a Pharmacy, Chocolate, Spooky Foods or Bookshop AB list. You won't get the really great items but you can still net yourself some good np until your account ages enough to use magic, stamp etc
Do Pharmacy; you can see all the items anyway. And when you say "safe" AB list... There's no such thing as a safe AB list. There's always the chance of getting frozen. And there's a thread of lists for almost all the shops (if not all the shops) in the Level 1 forum. Go check it out; it's a thread by Lightning. Great lists. EDIT: D= krilas you ninja.
