tried the demo version. it told me 3 times that multiple addresses were found for my specified address and no changes could be made. then the trial period was over ...
The new version 2.0 works fine with OS 10.6.7 and is a free upgrade for previous owners. Hint for previous owners: Don't just click on the MacUpdate download link or you'll end up with the demo version. Go to the developer's web site, enter your e-mail address used for the original purchase and you'll get a link for the full version.
I purchased this quite some time ago and I paid $5 for it as I recall. I have used it continuously ever since and it works flawlessly. This actually gets your snail mail delivered faster. Great little tool IMO
I was hesitant at first about purchasing a license, but in my correspondence with the developer I made the purchase without reservations. Those who know the USPS system also know that this little software jewel can literally save days in sending mail via USPS.
[Version 1.6]
