I did say SPOILER, so stop reading now if.
When Kristin Wiig looks at her now-closed cake shop at the beginning of movie, you can see some of the letters fell off the sign. But when she looks at the sign again later on, someone has graffiti'd an obscenity on the sign. Was that there all along, or was it just added for the later scene?
Also, did the bridesmaids have to pay for the wedding dresses they (presumably) ruined?
