Raul shipped the seeds to me May 19th and they arrived today. Customs checks the contents and leaves a note.
Not sure how long it "sits" in custom. My guess would be 2 or 3 weeks. Ive learned to not follow the tracking info too heavily because it usually takes a while to get out of mexico and then goes through customs. Besides Mexico other countries, like Australia, I would say its along the same lines of a month.
