Chainsmokers fans — a group the EDM-influenced pop duo refers to in a cool cigarette pun as "the Pack" — should start breathing deeply. The famous frat stars are selling merch this weekend at a dedicated San Francisco pop-up shop, timed to coincide with performances at Bill Graham Civic Center Auditorium.

The Chainsmokers, who now hold a once-prestigious Grammy Award, aren't in it for the music or, even the cash, as they confided in a much-derided Billboard Interview. “Even before success, pussy was number one,” said Pall, one half of the group, “Like, ‘Why am I trying to make all this money?’ I wanted to hook up with hotter girls. I had to date a model.”

If you share such aspirations or simply want to roll up the Chainsmokers' show in style, head over to 55 Wentworth place in the FiDi according to In-store raffles will be on going, with "the Pack" encouraged to check the hashtag #MDNOpopup.
