In the middle of the program Maura says that GMO saffron is $10 per pound v. $5000 per pound for saffron that's not genetically modified. Near the end, Jane says $10 per ounce v. $5000 per ounce. The per pound price is closer to the real price.
The x-ray shows wires inside the box suspected of having a bomb. Maura says she ordered a coffee maker and that must be what clicked, but there are only coffee pods in the box when it is opened, no coffee maker so there could not have been wires or a switch to click.
