Sent an email when the iMac is at a specified price

The other day a friend asked me to let him know if I saw a special offer of iMac. I don't wanna be watching every little time so I made a script.

#!/bin/bash

FILE=/root/no_mess
URL="http://store.apple.com/es/browse/home/specialdeals/mac/imac/27"
PRICE="1.395"

if [ ! -f $FILE ]
then

    LINE=`curl -s $URL | grep "${PRICE}"`

    if [ -n "${LINE}" ]
    then
        echo "Go to $URL" | mail -s "Ok let's go" my.personal@email.com > $FILE
    fi

fi

All that remains is to incorporate to the Cron.
