Dollar exchange rate?

[disney1sttimer]

Is it a good time to buy dollars at the moment ?

I never seem to get this right and everyone else always seems to get great deals. Where do you go to get dollars for your trips?

The rate seems to be going down at the moment but I have no idea whether you should wait or buy now. We were lucky last year when we got 2$ to the £ but it doesn't seem anywhere near that now. I use Crown Currency (am I allowed to advertise that mods?) and I found their rates about the best if you're looking long term
