For some unknown reason PopCap has just dropped the price of nearly every title in their catalog in an impromptu sale.

Perhaps it is to celebrate the big new update to the iPhone release of Plants vs. Zombies…who knows…who cares, just enjoy the savings!

The only title that wasn’t already priced at 99¢ (or Free) that didn’t get a price drop was Peggle HD, which is still at its special (50% off) launch price of $2.99. The Peggle Nights DLC is 99¢ (not sure if that is a sale price) for either platform.

Needless to say, if any of these fine games is still on your wishlist, now’s the time to buy! This goes double for Plants vs. Zombies HD which is $5 off right now!

UPDATE: We have a reason and a deadline: “To celebrate back to school, all PopCap iPhone & iPad games are on sale till Sunday!”
