Afraid this one can't be chalked up to April Fools.
Traxxas' prices have been on the rise. It was only a matter of time before the Power Up prices increased as well. The first (but probably not the last) Power Up Price increase is on the Velineon 1/10 Brushless System. Starting today, it goes up to $165 + $5 (for the shipping/handling). The selling price for the combo has risen as well, up to $199.99 (it you're buying it outright).
It's hard to recommend the Traxxas Power Up option now, given the price increase. Dynamite's Tazer offerings have been good for us, and at $129.99 (purchased outright, no trade-in required), the case for Traxxas' Velineon System just got harder to make.
