I don't get it

Bloomingdales opened in San Francisco this week. I only know this because I passed it on my way to school and people had lined up around a city block, waiting for the store to open. Hundreds of people. It's just another store selling shit people don't need. The shit will still be there after opening day. There will be future sales on the shit. I just don't get it. Is shopping for entertainment even more entertaining when one does it with hordes of people who storm the building en masse, like ants on a piece of turkey?
