How to do a "Related Products" block to your Drupal Site

I have been messing around with Drupal and with Shopping.com. While I know a module is coming from someone else, I am impatient. Also, a block is a nice concise chunk of functionality that doesn't pack on the weight or limitations that come with a whole module.


<?
$tids = explode(',',arg(2));
foreach ($tids as $tid) {
$term_info = taxonomy_get_term($tid);
$search_items = urlencode($term_info->name);
$items = simplexml_load_file('http://publisher.api.shopping.com/publisher/3.0/rest/GeneralSearch?identity.apiKey=[API KEY]&tr.trackingId=[LINKIN ID]&nf.keyword='.$search_items);

if (($items) && (strlen($search_items) > 1)) {
foreach ($items->categories->category->items->offer as $item) {
print '<div style="float: left; width: 120px; padding: 10px; overflow: auto; display: block;">';
print '<a href="'.$item->offerURL.'"><img src="'.$item->imageList->image[0]->sourceURL.'" width="100"></a>';
print "<br/>".l($item->name, $item->offerURL, array(), NULL, NULL, TRUE);
print '</div>';
}
}
}
?>


Here is an example it in action (scroll to the bottom).
