As a mom to boys, there are lots of video games in our home. I NEVER buy them new either. I always buy online. My favorite place to buy them is actually on eBay. I have found that as long as you are selective, you can get them cheaper than you can at a video game store. Another place that I have found is Craig's list. Again, you have to be sort of picky so that you don't end up spending more than you would at the store.
