A lot of times I have found that ordering online gives me a much better selection than going to a store. There are many games that are not selected to be held in store displays, but I would find a great game while floating the net. Also, some people find it safer and easier to have something shipped to their doorstep. I found this online store, which has a much larger game selection than Amazon. It also allows me to check to see if there are a series of games on a particular title.

I decided to put this up here for anyone's gaming needs. It is also a good research tool.
