Want to shop at a market where everything is FREE?! Umm, duh! You know what they say, one woman’s trash is another one’s treasure — and if you’ve ever been the lucky recipient of a barely worn beaut from a BFF’s closet, you know that to be very true. Score! is an event that wants to bring that lottery-winning feeling to the masses, but organizing pop-up swaps in cities across the country. If you live in the San Fran area, you’re in luck because you can participate TONIGHT (Thursday, August 21st) from 5-8pm at the Soma StrEat Food Park.

Here’s how the swap works. Snag a ticket ($10 in advance and $15 at the door tonight, $10 to $20 usually), bring your old stuff, walk away with free stuff from other people. It’s not a trade — you can bring an old purse you’re so over and leave with six cute dresses and a new book. The event is set up like a department store, so there’s a section for Music, Clothing, Art Supplies, Shoes, Books, Accessories and Housewares. When you get to the party, just drop off your goods at the corresponding departments and swap ‘til you drop… all while dancing to the tunes selected by a pretty sweet DJ, sipping a cocktail, socializing with the community and eating from local food trucks.

And even better? Your ticket for entry always benefits a non-profit org. Tonight’s swap is supporting Hack the Hood, which provides design training to low-income youth in the Bay Area so they can become makers.

Then anything that’s not taken at the end of the evening gets donated to Goodwill. Oh, and if you don’t have anything to bring, you can still participate! Buying a ticket is still helping ‘em raise moolah.

Brooklyn was the first home to Score! Pop-up Swap in ‘09 and three years later, they brought it to the West Coast. All Score! events take place with one common goal: To get rid of waste through partying. And no two events are alike; some have themes, some take place in warehouses, some are hosted in parks. To stay in the loop about future Score! events, sign up for their newsletter.

Partying, shopping and free stuff are all great, but Score’s purpose is what makes them really rule. Not only are they recycling old things, but they’re building a community and supporting local businesses. They’re essentially saving the world with free swag ;) Sounds like a fun, local part of a greater movement to look good while doing good, like this camera strap that benefits clean water initiatives or brands like Warby Parker and TOMS, companies that donate to those in need with every purchase. And those are all movements we can get behind.
