I may need some help. It could possibly be that these orders do not arrive together. In which case I can't claim empty box unless I say the part wasn't in the box. But that is hard to believe as the chance a part is not placed in a box/or stolen from  a box is low. Do you have suggestions if this 40g part arrives on its own to get a refund? Thanks.

EB should work regardless if it's in the same parcel or not based on the weight. There's a reason why so many SE are successful for light items like airpods based on the same principle.

Amazon are weird even when multiple items arrive at the same time they have their own box anyway more often that not. It's really rare in my experience for everything to arrive in one parcel.
