The placement of the land for Amazon is very strategic. Those warehouses don't just happen anywhere. Usually they are also very close to a freeway ramp because this makes it easier to get product in and reach customers. A lot of other businesses like Costco favor these same parcels for these same reasons. You'd think there would be a lot of places like this, but to be honest these sorts of huge parcels required for these businesses are rare and valuable real estate in cities. A lot of places are pretty built out already and getting a huge lot like that zoned for this use, let alone near a highway that's near a population center, is not an easy thing. I'm betting there are only a couple dozen sites like that available on the market nationally at any given time.
