Previous experience was not great. Here the post office is the only organisation authorised to perform customs tasks for incoming packages, so whichever package service is used, the package ends up with them instead of you. They will then proceed to damage your package as part of exercising their customs duty, take weeks doing that, charge you double for it and completely fail to send the package on to your house or notify you about its existence, assuming you are psychic. At least, that's what happened last time. I only got the package because another one was lost and in trying to track it down, this one turned up.

Which is why I usually order from within the EU or else from Amazon, since they handle customs stuff on the sender side.
