So, this is the function that will add something to the first paragraph, I want to add everything below after the_content on posts that are part of the store.

Sample function
<?php
function add_some_stuff($content) {
    $whateveryouwanttoadd = <<<PAYPAL
<form method="post" action="https://www.paypal.com/cgi-bin/webscr" target="paypal">
            <input type="hidden" name="cmd" value="_cart">
            <input type="hidden" name="business" value="$mama_paypal">
            <input type="hidden" name="item_name" value="the_title()">
            <input type="hidden" name="shopping_url" value="the_permalink()">
            <input type="hidden" name="item_number" value="the_ID()">
            <input type="hidden" name="amount" value="$price[0]">
            <input type="hidden" name="currency_code" value="USD">
            <input type="hidden" name="shipping" value="$shipping[0]">
            <input type="hidden" name="shipping2" value="$another[0]">
            <input type="hidden" name="handling_cart" value="$mama_handling">
            <input type="hidden" name="bn"  value="ButtonFactory.PayPal.001">
            <input type="image" name="add" src="http://www.powersellersunite.com/buttonfactory/sc-but-01.gif">
        </form>
PAYPAL;

        $content = preg_replace('/<\/p>/', '</p><p>'. $whateveryouwanttoadd.'</p>', $content, 1);

    return $content;
}

add_filter('the_content', 'add_some_stuff');
?>
All of this is the paypal link stuff that needs to be added.
