Kim Kardashian Buys Up All the Vogues But Why Now?

Kim Kardashian cannot get enough of herself ... hitting up a newsstand on Tuesday to buy up every issue of her Vogue magazine cover she could get her mitts on ... but why did she wait three weeks after the magazine hit shelves?

The video might answer the question ... as she and Kendall Jenner go rifling through the magazine racks, a camera crew (most likely from her reality show) is tracking their every move.

So maybe it was just a cool moment -- Kim celebrating a historic career achievement.
