Paying For PCalc
You can buy PCalc through Apple's Mac App Store.
If you have an existing iTunes account, it's pretty much a one-click purchase. The application will download and install automatically and the store will keep you up-to-date when we have any new versions out. There are no serial numbers to keep track of or anything like that.
