lamicrogroup rip off

I just came across tonight and had a look their prices and its more expensive to buy from them than it is to go buy from the dell outlet.
Much to my astonishment I then came across which has the exact same products and the exact same website except the prices are in dollars. What knocked me for six is that all the servers are half the price of the uk models.
This begs the question, are they ripping off uk customers? It certainly looks like it to me.
