I want to send a birthday gift, and I need it to be on time, exactly on my friend's birthday. so what kind of post I can use? or is there any kind of company that I can order Online from US, and the gift delivered in UK?! I mean they bring the gift to my friend.I want to post a parcel, and the delivery time is very important, what post I can use?
I suggest Fed Ex or UPS rather than the postal service.



However, ensuring an exact delivery day for international shipments is not always easy, so don't count on it. The big problem is clearing customs, because you never really know how long it will take.



So - call the Fed Ex customer service number, for example,

and ask them about doing this.



It _might_ be possible for you to send it many days in advance, to ensure that it clears customs in time, then have it held in a local depot until the day specified for delivery. Give them a call.



This is the UPS contact info:

DHL also ships internationally:
