Wait, why are your packets of seed arriving empty all the time? Customs declaring them exotic and harmful? Mulberry mobsters? Moths in the delivery chain?
Silkworm eggs, not seed. Got my refunds. No clue. Domestic, wasn't shipped from overseas or anything, and if it was customs they usually send something saying that they're confiscating the shipment (or so I'm led to believe, I don't often try to smuggle anything). It was a bit weird. They were pretty good about delivering the empty ripped envelopes though.
