I was telling someone that
www.cdwow.com are doing free European flights if you spend over £18.00 (offer ends soon).
As he pointed out, many European destinations are virtually free anyway with RyanAir or Easyjet. His daughter was going to Holland over New Year for £9.99 there and £0.99p back (plus taxes of course).
And the funny thing about CDWow is that a lot of their goods are £17.99 - so you end up buying something small you didn't really want, just to get the free flight. I know, I did!
