Although slightly better exchange rates were available from a couple of London exchange dealers I felt more comfortable with the SUYC system of providing a prepared registered envelope to send them my Euros. It proved that there was someone at the other end! I emailed SUYC on Monday, received the prepared envelope on Tuesday and sent the cash. Early Wednesday I received an email confirming receipt of the letter and later in the day another email confirming the amount received was correct and that the transaction was being processed. On Thursday morning I received my cheque. It could not have been easier.
