Do you pay import duties in the UK on items purchased for personal use? The situation is changing constantly in the US, but generally speaking you do pay duties only over a certain dollar amount in value if you intend to keep the item in country after importation (and a MBP would be over that amount), but it's a fairly small percentage (around $400 in duties on $3149 saved here). I'm not sure how it'd work in the UK.
