Hi, just thought I'd throw my two cents in. All of the SE's have new link filters in place. You will definitely get smacked down hard if you get hundreds or thousands of links from one domain all at once.
From my experience only one link from another url is even going to be counted by the SE's. Yahoos! Site Explorer will give you an idea of how many links you have from each url.

We have approximately 5,000 links listed in Google Webmaster and Yahoo Link Manager from this particular site?

Oh No! All with the same link text?!

Yes you will be in the link spam radar now for a little while. One categorized link per url is all that will do any good. And if you are going to purchase a link like this ask that one link be placed on a high ranking and high traffic page. This way hopefully the link will bring you traffic and Google love. However 5,000 links suddenly appearing may bring you traffic but not SE love. Look at this from their point of view. You or an alias could possibly own the other url, besides it being an obviously purchased link. Or you could fast track a blog to create thousand of outbound links(there is software to do this so G,Y, and M are on the lookout).
You are better off getting listed in second tier directories(one way of course, might cost ten bucks) if you are trying to boost your rankings. Also, if you can have a competitor with a higher ranking than yours swap links with you(reciprocal linking is not dead just stay on the focus of your site and don't bother if you are going to be on links_42.php).
I would either demand a refund, you have been taken advantage of!, or demand a link on their home page only.
Just speaking from experience hope this helps!, Dan
