A post in another thread asked us to post these so I figure a separate thread is the answer. Here is a site I use when looking for deals. If you register you can set a notice using search criteria.
Slickdeals
A filter using PS1 PS2 PS3 or Xbox should return good results. You'll get chaff with the wheat, but I've found some good deals there. That is where I found the $229 500GB PS3 with AC3 that I bought.
I did a search using the box at the top left of the main page using PS3 and threads. It returned close to 8k hits. That search with the word games added dropped the number to under 7k.
Still a large number...
Ah, found it. At the left on the advanced options page there are more filters. Adding the one for just the last two weeks brought it down to 77.
