Inserting affiliate links from say LinkShare or Commission Junction into your Joomla content is not really difficult.  I already wrote an article here detailing the code needed to implement Commission Junction Web Services using REST.  So, several things to layout:

1. develop your REST API using the code I provided here (this includes the REST and the call API)
2. install the Sourcerer plugin for Joomla found here (this provides the ability to interpret PHP)
3. remove the 'exec' restriction for the Sourcerer plugin or the rendering will be a blank article (do this under plugins - system - sourcerer)
4. create a new article with whatever and/or the call API code (ensure the call API code is inserted with the Sourcerer button)

A couple notes on developing the REST and call API's.  I spent quite a significant amount of time developing mine, deciding what CSS to use to overcome article rendering issues (keeping things from jumbling up or simply rendering in such a way that was visually unacceptable.

Another plugin that would seemingly work is called DirectPHP.  The problem with DirectPHP is that when it is activated, it tries to execute ALL PHP.  Since I put PHP in my articles so that people can see the code, this plugin did not work for me.  Sourcerer is a case by case implementation, not a global site one.

I am using Geshi for my code highlighting.  Geshi does a great job with that, but not so much for wrapping very long lines of code.  There is a solution, however.  I found this solution works with IE 8.0.6001, FireFox 3.62, Opera 10.51, and Chrome 4.1.249.

If you are using feeds from DataFeedFile.com and need a workaround for the "URL file-access is disabled in the server configuration" problem, one way is to create a php.ini (or add to your existing) in the root folder of your site and add the following two options:  allow_url_fopen = Off and allow_url_include = On.  If these are not options for you, then you might try using PHP's cURL library instead.

The standard PHP code to embed DataFeedFile.com's feeds is (example only - your URL will vary, i.e. your affid and product_sku):

<?php 
include('http://www.datafeedfile.com/dffphp_script_prdtmain.php?
dffget_affid=5542&amp;dffget_style=2&amp;dffget_nw=1&amp;dffget_dff_product_sku=2537819
&amp;dffget_dff_pse_url=http%3A//path_to_your_price_search_engine&amp;'.$_SERVER['QUERY_STRING']);
?>

Workaround:

<?php
$ch = curl_init('http://www.datafeedfile.com/dffphp_script_menu.php?dffget_affid=5542
&amp;dffget_script=menu&amp;dffget_page=cat&amp;dffget_style=2&amp;dffget_cols=2
&amp;dffget_rows=12&amp;dffget_fontsize=10&amp;dffget_view=listplus
&amp;dffget_targeturl=http%3A//path_to_your_price_search_engine&amp;'.$_SERVER['QUERY_STRING']);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
if(($DFF_output = curl_exec($ch))===FALSE)
die("Error getting content...please try again in a few minutes"); else echo $DFF_output;
curl_close($ch); 
?>
