I thought I'd give everyone a heads up for this one: from today (10/12) till Saturday (10/18), there's a buy 2 games get 1 free deal, for all systems.
The more interesting sale to me, though, is that for today & tomorrow (10/12-13), Wii accessories are 40% off. This includes Wii points - I just bought 6000 online for $44 (including tax & shipping). It'd be more convenient to find it in a store without the shipping costs/delay, but it's still much cheaper than normal. Looking forward to playing World of Goo...
edit: I forgot to mention this doesn't include Wiimotes or nunchucks, sorry.
I know this is U.S. only, but hopefully enough of you can find use out of this to clean them out of their Wii points cards.
