I'm a frequent buyer/seller to US, wanna share some of my experience with you guys.

USPS Priority is not the fastest way as it's stated on their web, it said 6-10 days but in fact it will take more than 2 weeks to arrive here in malaysia.

Usually i will go for First Class, more cheaper and it's takes the same time period with Priority Mail.

But, international shipping is really depend on your luck. Sometimes i got First Class arrive within 7 days and same with Priority.

And USPS have the cheapest and the slowest way which is via International Ground. I have 3 parcel from US sending with that service (which is the seller fault). And it will takes 1-3 month.. My suggestion never ever use that service if you buying from the states, unless you're really patient.

The fastest country delivered in malaysia on my experience is France, UK, Sweden, Australia, Taiwan & Hong Kong.
