Pre-Paid Card versus Subscription,
This review is from: World of Warcraft 60 Day Pre-Paid Time Card - PC/Mac (Video Game)
Currently a subscription to WoW costs:
$15 a month on the per month plan, $14 a month on a 3 month plan, $12 a month on a 6 month plan, this 60 day prepaid at $23 (23% off on sale) works out to: $11.50 per month!
Other then being cheaper (at the moment) if you go with one of the extended (3 and 6 month plans) and decide to quit the game there is no refund for unspent time. On the 3 month plan you're going to be out $28 (for 2 months) at worst and on the 6 month plan you could be out $60 (for 5 months) if you quit in the month of the billing cycle.
So your costs are less, and so is your exposure. The only drawback is: you'll need to get another card in 60 days or sign up for the month to month plan while you wait for your next card to arrive.
It turns out, month to month is cheaper then anything, except the 60 day card, if you count money lost when you decide to quit the game but have a couple of months outstanding.
