Having ordered a product from the US, shipped on Thursday, September 13th, it was delivered to me 5 business days later, on Wednesday, September 19th, in Singapore.
That's exactly what was expected and paid for with Fedex International Economy (US$ 36.88 in this case).
The interesting part is that the package was actually in Singapore 2 days before delivery, Fedex keeping it on hold for 1 day and a half.
I believe that it is because I did not pay the additional US$3.90 of the Fedex International Priority service, which guarantees a 3-day delivery.
For 44 hours, my package remained in the warehouse, not to be delivered earlier than expected.
