PostPoints tip: Discounts at Apple's Mac App Store (and their costs)
If you're running the current release of Mac OS X, you can score some tidy discounts on Apple's own software by buying through its one-click Mac App Store. For instance, while the company's new iLife '11 multimedia suite goes for $49 in its own stores, you can buy its three updated applications--iPhoto, iMovie and Garage Band--for a total of $44.97 through the App Store, or, better yet, you can pick only the new iLife components that you want. Similar savings exist for Apple's iWork '09 bundle, which costs $79.99 at retail and a combined $59.97 through the App Store. But realize that you can't resell App Store purchases unless you share your store username and password with the buyer, while no such barrier stops you from selling a CD or DVD of those programs (as I've done twice on eBay).
You should consider a different issue with software from third-party developers: Apple's 30 percent cut of each App Store sale probably exceeds what their older payment processors take on each sale. So if you're fond of a Mac software shop's work, you may want to stick to its existing Web storefront, even if it's not as elegant or seamless as the App Store.
* Sunday's column recounted my experience relying only on over-the-air broadcasts and Web video for my TV viewing. Short version: It's worked out surprisingly well... although I'm not sure if having no trouble watching the Redskins find new ways to lose on Sundays and Mondays is necessarily a plus.
