Ordering from Darker Than Black

I’m new to buying vinyl. I want to order three records from Darker Than Black. I think I’m just stupid but the shipping options are a little confusing to me and I don’t know which one to choose. Could you guys help me out? I live in the USA by the way.

1. Commercial mail - KEIN Versand von LP + MLP in Deutschland!
2. Parcel Delivery
3. DHL + cargo insurance

Sorry if this is a REALLY stupid question. I don’t buy a lot of things.
