A perfect software product

Summary
This review was originally posted on VersionTracker.com.<br />So rare. It works simply, yet it has all the options you could want, including not going ALL CAPS, the way the post office likes to do it, not abbriviating Road as Rd, etc. If the address needs a zip, it gets a zip. If it needs a city or state, it gets a city and state. If only all software could be this good. Think of your $10 payment as your own little mini MacArthur grant.
Wonderful plug-in

Summary
This review was originally posted on VersionTracker.com.<br />Tried out the (nearly) full-functioning demo after I saw PostCheck mentioned on some forum more than a year ago. Got hooked on the convenience and bought a license. Glad I did. It's one of those niche-filling pieces of shareware I use frequently...every time I add an address to my Apple Address Book. I suspect sales would increase significantly if it were priced at $5 but I'm still happy I licensed it. BTW, Brian, you should work with MacUpdate to offer it for one day at half price on their daily special board and see if a lower price (with higher sales) maximizes revenue on your particular product. I just have a feeling that $5 is the sweet spot.
Fantastic Plugin and and works great with OS X...

...10.5.2<br />This review was originally posted on VersionTracker.com.<br />This is a fantastic plugin! I am a heavy user of Address Book and this piece of software is a massive time saver. I realize some people may find $10 a little high for what this does but I would suggest they are not the targeted audience for this. If you make frequent use of Address Book then this plugin is for you. It couldn't get any easier. Works great with Leopard.
Excellent plug-in!

Developer’s Description

Address Book plugin for finding ZIP codes & standardizing address formats.

Is an address missing a ZIP Code? Do you know the ZIP Code, but you're not sure what city it's for? Look up your missing address information with a single click, rather than visiting USPS.com each time. PostCheck will also reformat an address to conform to the United States Post Office standards.
