In the party scene at the bowling alley when they start opening the presents, they open two: Becca's and the mom's present.

When Becca walks into the room that is off of the kitchen to bring Izzy her crème brûlée, one can hear the door shut behind Becca, and in the next shot the door is completely shut.
