Summer is the season of pop-ups, and San Francisco-based online reseller Twice is joining the party. For two weeks, from June 18th to June 30th, between 8am-8pm, Twice is setting up shop at a busy Castro intersection and inviting the locals to de-clutter by dropping bags of clothes, appliances and more.

This is an unusual venture for Twice, even given its recent experiments – since the beginning of the year, the website hosted featured online stores by star blogger Erin Halstrom from Calivintage and the Warriors finest, Adre Iguodala. Not only that the brick-and-mortar space doesn’t offer anything for sale, it’s also accepting much more than clothes, the reseller’s only category until now.

“We are excited about testing a brick and mortar concept, and since it’s a physical store, we’re giving customers a chance to drop items that are harder to ship”, says Chris Luhur, Twice’s Director of Marketing & Community. “People are invited to drop off home goods, musical instruments and pretty much anything under their roof”. Luhur doesn’t deny that in the future, this current experiment may lead to expansion into home goods categories online, as well as to permanent physical stores.

As part of the promotion, Twice introduces a couple more exceptions to their policy – San Francisco residents can order a free Postmates pickup, if too lazy to stop by, and get a price offer within 24 hours. Don’t like the offer? Take your stuff back, or reclaim whatever Twice doesn’t accept. “I encourage everyone to do it – it’s risk free, since you can always take back anything we rejected”, says Luhur. “De-cluttering frees up space in your place and calms the mind”. With San Francisco’s studio apartment reality, it can also be a necessity.

The Twice pop-up store is located at 410 Castro Street.
