CityVille: Redeem Game Card, receive 20% extra City Cash

Zynga is throwing a Game Card "sale" in CityVille this weekend, lasting from now until March 20 (that's tomorrow) at 11:59 PM PST. For all users that redeem a Game Card or eCard for City Cash in CityVille in this time period, you'll receive 20% extra City Cash on your transaction for free.

To be specific, the full value of your Game Card (whether it be $10, $20 or otherwise) will be redeemed when you take part in this promotion - you'll just also receive a few extra City Cash on your account for turning it in during this time. As another bonus, if you redeem a Game Card, Zynga says you'll also receive extra bonus Energy, but they didn't clarify just how many energy points you'd receive. Still, with the recent changes to the availability of energy, any extra energy is better than none.

If you had been planning on redeeming a Game Card but were waiting for a good reason, here it is. Remember, this deal will only be available until Midnight tomorrow evening, so make sure to take advantage of it while there's still time, if you're interested.

What do you think of this new promotion? Is 20% too little of a bonus to have you purchase an eCard, or did you already receive your bonus City Cash and energy? Let us know in the comments.
