How long Apple takes to deliver MBP in UK

Hi, I dont know where to ask this question and also not able to find answer in google. I ordered my Macbook pro on Monday, 19th January. On Tuesday 20th, I received shipment notification. They mentioned that I will get my items on or before 29th January, next Thursday. I would like to know when will I get my items.
I am from Oxford, England. Hope to hear from people from UK.

Usually UK online stores deliver items next day itself. I saw a photo of Macbook pro in Flickr. In that they mentioned that they (they are in Europe, I guess) got the Mac from China in 3 days. Does Apple ship its items from China only? I thought they would send from London or some other nearby cities for the UK customers. I just curious to know this.

Thanks in advance!
