The only problem with using FedEx or DHL is that the package can get stuck in Bangkok, at the airport customs office. believe me, you don't want this to happen. The person the package is addressed to has to clear the package... sometimes having to physically go to Bangkok. It's a hassle. It's been my experience with packages that have been mailed to the gym that the best service is from the normal mail (national mail service). If you want the package to be delivered quickly just pay for express service, but avoid FedEx and DHL.
