19-year-old "Hunger Games" star Josh Hutcherson took a not-so-cheap shot at a Ralph's Grocery store -- he posed as over 21 and got the check out clerk to sell him an expensive bottle of whiskey.
We got this pic of Josh leaving the Ralph's in Sherman Oaks on April 18 with a bottle of Macallan whisky in hand -- which, by the way, goes for $170.
A source tells TMZ ... Josh used a fake ID to score the bottle.
It's interesting ... a few weeks ago we got Josh on camera, grousing, "I think the age to go to war is 18 ... so I think the drinking age should be 18 as well."
A spokesperson for Ralphs tells TMZ, "We strictly enforce all laws relating to the sale of alcohol to minors. We will investigate these allegations and take any steps necessary."
Josh could be prosecuted and the maximum punishment is 6 months in jail, although in reality he'd spend no time behind bars. Authorities could also go after Ralph's for selling to a minor.
We reached out to Josh's rep. So far, no comment.
