Mac prices U vs UK

Anyone know how much cheaper it is to buy a MacBook Pro (or any Mac product) in the USA compared to prices in the UK? I heard it's a huge difference, but just wanted to double check! Thanks.

Official Apple Store - Buy iPhone 5s, iPhone 5c, iPad Air, iPad mini, MacBook Pro, and more

The Official Apple Store (United Kingdom) — iPhone 5s, iPhone 5c, iPad Air, MacBook Pro and more

As example, take de Mac Pro
US $2999
UK £2499 but using conversion should be £1835
€uroland €3049 but using conversion should be €2200

This is a really simple comparison, other factors may affect but I am not an economist :D

Euro prices include sales tax.

If you buy in the States and import to the UK, you're required to pay sales tax and import duties at customs.
