I think it could easily have happened that way.
But even more: Scott was talking to Amber so much, even in Carmel, and one wonders if Laci noticed his phone calls while there. I mean, maybe it was there that she first noticed that he might be cheating.
The maid did say Scott came "back" to the house at 10 a.m. on the 23rd, to get a Fed Ex. I assumed he had successfully gotten it... ? If he hadn't gotten it at that time, but knew that Amber had sent this "bomb" to Modesto, wouldn't he have stayed glued to the house, so he could quickly intercept it? ("Just a customer sending something, dear.")

Your right he would have. Unless, he was unsure of the package or thought it was more important to be in Sacramento. There was a Fed-Ex delivered on the 24th as well.
