Are there any codes to get red bricks? Things like Money x2, Invincibility, etc.

Thanks!

You really don't need them. you get the first red brick (x2) by finishing the fountain in Bricksburg. X4 is in wild west (just locate the 3 bank robbers). With those 2 alone you get 8X enabled. Not to mention, the DLC gives you prospector pants which almost doubles the amount you collect from breaking things. Google is your friend!
