\opening{Dear Woodworm Records,}

I seem to have ordered the wrong ticket
for this year's Cropredy festival.  I intended to order
a full weekend ticket, but I must have specified a Saturday-only ticket
by mistake.

I hope you will be able to exchange this ticket.  I'm including
the ticket, together with a cheque to cover the difference
in price (\pounds 27 $-$ \pounds 18 = \pounds 9).  Apologies
for the inconvenience,

\closing{Yours sincerely,}

\end{letter}
