Besides the Welcome bonus described earlier, as soon as you open an account on Pacific Poker you have the right to participate to seven Freeroll tournaments, each one of a $500 registration fee. The tournaments are called  Depositor's Freeroll and are daily organized.
The invitations mentioned above are being sent to you immediately after the first deposit, no obligations for playing before acquiring them.
But it does not end here. If your first deposit has been one $50 or more, you will also receive a free invitation to join the $1000 tournament, always dedicated to the new Players (from what said so far, you can guess that the level of the players is not highest:)
To sum it up, for the current moment, by depositing a sum equal or higher than $50 you get:

• The welcome bonus.
• The free entrance to seven tournaments, each of $500 of value.
• The free entrance to a $1000 tournament.

Not bad at all!
