I preordered also. One deck I won plus three decks I bought. $30 for EMS shipping. This is NOT cheap shipping by a long shot, but the Philippines are an island nation and not exactly next door to the US. It's on par with what I paid for shipping of the Bicycle Clot decks when I bought them out of Taiwan.
In fact, Clot is from Hong Kong, not Taiwan
Taiwan PO provides Airmail (like USPS first-class mail) and Priority Parcel (like USPS Priority Flat Rate Box), these 2 shipping methods are cheaper than EMS and effecient (and trackable). Normally we don't need to use EMS. For example, shipping 4 decks to US costs $8.5 and takes 6-8 days, and it is trackable until it is delivered.
I still feel $30 for 4 decks with EMS is overcharged, unless insurance is included. I just looked up the table, from TW to US with EMS, $18.5 for packages under 0.5Kg and $23 for packages under 1Kg.
