I recently bought a watch from a seller in Thailand. There were two options for shipping: regular airmail and EMS. The regular mail was $15 and EMS was $35. I opted for EMS because they are super fast and have never failed me, and this isn't a cheap or easy to find watch.
I got a "marked as shipped" notice with a tracking number today, and the number starts with RR. I am used to EMS packages starting with EE. Is there a different code for some countries or did the seller send by registered mail? I am asking here because my online search provided little information and I want to make sure I know what I am talking about before contacting the seller for a refund.
