Ubisoft's DS guitar ... thing Jam Sessions has dipped down to $20 before as part of a sale, but now the drop is permanent. Both GameStop and Amazon are now selling the novel virtual instrument at a $19.99 price point. As a bonus, GameStop has also dropped the price of the Nyko JAMMIN' Guitar Pick Stylus set, from $7 to $5. A fake guitar pick seems like an appropriate accessory for a fake guitar.
Now, for the same price, you can have an all-DS trio instead of an all-DS duo! Just in case the lack of a third bandmate was the only thing keeping you from starting a Jam Sessions-only band.
