My thanks to Brian Toth for sponsoring the RSS feed this week to promote his excellent PostCheck.

PostCheck is a killer plug-in for Address Book on your Mac. Its goal is to properly format the addresses in your Address Book for shipping things with USPS. The killer (for me) part is that it will autofill in that pesky 4-digit addition that fancy people add to the zip codes.

I dig this plug-in, it’s not something I use all the time — but it is something that just seems so Apple-like every time I use it. Why this is not a built-in feature I don’t know.

At $10 it is an instant buy in my book.
