Diary of a Wimpy Kid: Rodrick Rules (Three-Disc Blu-ray/DVD Combo + Digital Copy) (2011) for $12.99

Brothers aren't supposed to get along, so it should come as no surprise that Greg and his older sibling Rodrick fight continuously. However, their mother has a different idea about what the relationship between two brothers should look like, and she writes a column about it for the local newspaper, so she should know. Never one to let nature take its course, Mom tries a variety of strategies to get the boys to bond--everything from the incentive-driven "mom bucks" to punishing them by leaving them home together for the weekend while the rest of the family heads to the water park.
