99PVZ
BigFishGames is doing a promotion on the Plants vs. Zombies on either Windows or Mac. Use promo code 99PVZ to bring the price down to 99c USD (from $9.99). Good for those who did not manage to get it for free last year.
At the checkout make sure you change the currency to USD and pay for it using no foreign currency transaction fee cards such as 28Degree.
I just use Paypal
