Personal Money Store will buy 525 word articles on specific finance topics. Articles must be previously unpublished. Pay rate is around 5 cents per word (approx $25 per article).
They do insist that you research their preferred topics thoroughly and include their chosen keywords several times throughout your article.
Keep in mind that the type of comments already shown on Personal Money's blog post show you the level of writers they're not really looking for (you know the ones - the comments from people that say fun things like "plz tell me how to start I write good english plz tell me how to get payed" - and then these same people wonder why they're not getting paid. Go figure.)
These kinds of comments tell the editors who will be paying out good money for quality work exactly what kind of writer you really are before they even read your article. The submission instructions are clearly written on the page. Read them. Understand them. Write your article and then submit.
Here's the writer's guidelines page:
