They actually deduct the VAT when shipping to the Us, so they can be quite affordable.
It's always best to compare though. Every store has different mark ups on different styles.
VAT is Value Added Tax, which is currently 17.5% of the cost of the item. It is normally added on to give a final cost price but can be removed if the item is going abroad. Obviously, you may have to pay Import and local taxes on delivery.Whats VAT?
And how do you order?
^ You have to email them to order. I've ordered from them before- all you have to do is click the "email us to purchase this item" and write the style and size you need. That should work.
