Looks like it's the way you've pasted in your links.
A load of themlook like this:
<a href="http://<a href="http://store.eSellerate.net/a.asp?c=1_SKU49243943998_AFL8994387948&at=">Buy Bread Machine Cookbook Ebook Only</a>" title="You name it bread reciepes for bread machines">The Ultimate Bread Machine Cookbook</a>
At a guess, you've been given the code to insert in a page to add a link with link text, and you've pasted all that code into the link box instead of just the link itself.
So where you should have put in:
You've put in
<a href="http://some.link.com.wotsit">click this</a>
And WP has wrapped that whole thing in
<a href stuff that it normally does.
