Question Using sed with bash variables

Hi Guys

I have another problem I'm trying to solve and hope that some one can help me here.

This is the scenario:

I have a file and I want to add a line on the 3rd line of the file using a bash script. but instead its adding the the bash variable $WEBSITE.

Below is the bash script I'm using.
Code:
#!/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11

echo "what is the website ?"
read WEBSITE
if grep -q $WEBSITE "/etc/squid3/acls/allowed-sites"
then
        echo "$WEBSITE already exists"
else
        echo "adding website $WEBSITE"
        sed -ie '3i\$WEBSITE\' /etc/squid3/acls/allowed-sites
        echo "restarting squid"
fi

I have tried a few different ways of doing this with sed but nothing works.

Please help.

Please wrap all code, files, input & output/errors in CODE tags.
It makes them far easier to read and preserves multiple spaces for indenting or fixed width data
