The Mac App Store has been a great place to find bargains, and today brings another one that I'm pretty excited about: Plants vs. Zombies is available for US$10, instead of the $20 that PopCap has charged on its website.
I've seen several apps that have offered significant discounts in the Mac App Store, such as Little Snapper, Pixelmator, Aperture (which sells for $80 despite the fact that Apple still offers to preinstall it on Macs for $200!) and more.
Have you found any great discounts in the Mac App Store versus previous prices? If so, let us know in the comments.
