Just two days after taking son Pax to buy a $900 sweatshirt at YSL, Angelina's back on a budget with daughters Shiloh and Vivienne and son Knox, taking them to a discount shoe warehouse to stock up on new kicks!

Jolie was radiant and smiling as she shopped with her young daughter for art supplies, as well -- it's the family's usual outing when they're bored on a weekend afternoon. And hey, why not make art?!

Seems Angelina is unfazed by ex Brad Pitt's recent reconciliation with his ex-wife Jennifer Aniston at her 50th birthday party. Hey, maybe it gets him off her back! And maybe these two will be friendly one day ... like at Jolie's 50th birthday in seven years!
