When Vera is displaying mannequins in front of her store a car
drives by hitting and dismembering the one in the blue/green dress, but when Roger and Peter are bringing the mannequins they only bring in the red one which only lost one leg.
When Christina sits down to read the 10 commandments she breaks off a piece of the cookie. When the girls come into the room and Christina is crying, the cookie on the plate is whole.
When Courtney is driving the car and Christina is looking under the driver's seat, the close ups show a four-lane road, while the aerial shots show only a two lane road.

When Christina and Courtney are in the car on their way to the wedding, they look at their map and mention taking Interstate 95 and 40. Those interstates are located in the east coast. Interstates near San Francisco are 680, 880, 80 and 280.
When Peter turns the pages in Vera's mailing list guest book and lands on "Christina Walters loves Peter," the zip code written is "94587" which is the zip code of Union City, California, a smaller city in the East Bay area.
Somerset is east of Sacramento. They would need to take 80 and 50, not the highways they were talking about. Not to mention, the area code there would be 530, not 510 like on the bench billboard (510 is for the East Bay).
The zip code for their address in Vera's book should be 94133.
