If you were considering getting a DSi XL -- even for just a single, momentary second -- and you live in, near or around Canada then you should probably pick up five relatively new games you aren't playing anymore and head to your local (or not so local) Best Buy. For five used games you can get a DSi XL for free.
The titles must have a trade-in value of at least $9, which probably means it is restricted to newer releases and popular games, but that is still quite a deal if you're done playing them anyway. The official rules and games that are eligible for trade-in can be found at Best Buy Canada's site.
Despite the fact that I horde games, live in Washington, DC, and previously said I wasn't getting the DSi XL, I may head up to Canada right now. Well, not really.
