My mother lives in Shanghai so I don't know if it would be the same where you are shipping. FedEx and UPS were much more expensive, took longer and ALWAYS got stuck in customs (for weeks). I used the USPS with the EXPRESS delivery (would be overnight here in the US) and it was always there in in four days, less than the guaranteed time, with confirmation and weekend delivery (and this was for dozens of successful packages).
