Heads up, Boulderites — today’s the day to grab that pile ofreusable grocery bags piling up on top of your fridge and move them to your car. Why? Because effective today, grocery stores in Boulder will be charging you 10 cents for every disposable grocery bag in the checkout lanes.

Now, before you get all in a huff that you’re actually going to have to pay for the bags you scoop the litter box and dog poo into, Boulder’s got your back. The City will be doing giveaways throughout the summer at various shopping locations (details below), offering up free reusable shopping bags to the Boulder public. The ones featured in the video below are pretty sweet — I’m personally a fan of the canvas ones over the funky fabric ones.

If you want to score one of those free shopping bags, today just happens to be the day! Here’s a list of times and locations where you can build your ownreusable shopping bag stash all around the Boulder area (information courtesy of the City of Boulder):

• 11 a.m. to 1:30 p.m.: All Boulder Safeway & King Soopers locations
