Americans on the East Coast were flying over to London for weekend shopping trips. Didn't last -- these things never do!
I made 3 shopping trips to the US this year from Germany, and honestly even the the dollar recovery its still a good deal to fly over for a few days.
On the topic of the Pound, against the Euro its really looking a bit of a disaster these past few days...ever since the last rate cut....against the USD, don't think that comparison is relevant anymore, based on the increase in credit/debt with all the bailouts...basically the dollar is being devalued but don't expect an announcement on that one until AFTER it has happened.
The astute amongst you may well ask, devalued against what exactly?
