It depends on the package, but generally I would at least us a bunch of anchors and link to inner pages and the home page. If you order anything larger then the bronze, then I would include Tier links as well, as this is a lot of links. Unless you have a excellent and robust link profile already. Ive never had anyone penalized, but if you pump too many links at the main site and its out of proportion with what google is used to, your site will dance all over the serps for several days to a few weeks, or it can anyway. While it will settle down, in the mean time you can lose revenue so its better to be safe then sorry.
