I think Eddie was pretty straightforward when he said that it cannot be used in any commercial applications. Commercial meaning that money changes hands (or accounts). If any money is paid for the service built upon the Placefinder data, that constitutes commercial use.
For that, you would need to look to some commercial APIs such as Cdyne, StrikeIron, QAS, and SmartyStreets. That is not an exhaustive list, there are a lot of them out there. Just do a search for "address verification api" or something similar.
There are also some free geocoding services out there. Here's a really good one from
USC. If your organization is a non-profit service, then
SmartyStreets has a free one as well. The USC site has a
very good service, especially for smaller volume needs.
It wouldn't be fair if I didn't point out that I am not completely impartial. I do work for an address verification service called SmartyStreets, but I do try to pass on knowledge and experience that I have obtained and not just make shameless advertisements.

I'm trying to build a store locator app as well, and would like to store lat/long in a database in order to calculate distance from a location. Can I get a staight forward answer as to if this is allowed by the PlaceFinder API? Thanks in advance.
