There are many places in SL that have special offers, freebies, and complete avatar packs for new users. If you are a new user look for free starter packs first and shop around before spending a lot of money on skins, shapes and hair. It's always wise to try demos first, and remember that how a skin looks depends on your shape and vice versa. A shape will not look the same when you wear it as it does on the box unless you have exactly the same skin on.

This list is of good places for new users.
