FarmVille: 20% off Game Card sale for a limited time

As a way to send the second birthday celebration in FarmVille out with a bang, Zynga is throwing a 20% off Game Card sale on all Zynga Game Cards redeemed in the game this weekend. I've said it before, but the word "sale" here really is a poor choice. The way these Game Card promotions work sees you spending the same amount of money (say, if you were to walk into a retailer and spend $25 on a Game Card), but you'll just receive more Farm Cash than normal when you redeem it.

That nitpick about wording aside, this is a great opportunity to stock up on bonus Farm Cash and earn free Mystery Darts just for redeeming a card. This sale will only last until Sunday evening at 9PM PDT, so make sure to redeem your Game Cards now if you've been holding onto one for such an event.

Will you buy a Zynga Game Card to stock up on bonus Farm Cash in this promotion? Let us know in the comments.
