Not so fast! They say:
*Rate promise: The rate will be a minimum of 3.25% over European Central Bank (ECB) until 01/06/2009, thereafter the rate will not be less than ECB rate until the 30th of April 2010
Granted ,the guarantee of of ECB+3.25% has expired but that does not necessarily mean that the rate has dropped to ECB + 0%. The rate could be anything. All they have done is remove the guarantee, as it hs expired. For all you know the rate could be 11%!. Their website still quotes a rate of 5.25%. Check what the actual rate is before rushing off to close the account.
