I would very, very gladly live in a Costco apartment complex above a Costco store. Being able to buy Costco rotisserie chicken, ribs, and pizza anytime? Sign me up!
Pentagon city metro is right next to a Costco. Close enough?
What about Costco law school?
There is a Trader Joes with a apartment complex above it in Milpitas, CA (in the SF bay area). I've seen that in my city too but it needs to become more common.
I used to live in an apartment complex with trader Joe in the westwood area of LA near UCLA. Oddly enough, I would walk over to the whole food’s or Ralph’s instead to grocery shop (but everything was walkable, even the target across the street).
I would end up eating nothing but Costco hot dogs. When are they doing this in the south SFBA? Sign me up.
