Buy for Web Use : Small/Medium Business Package:

To extract Address information at Full Address level, Thoroughfare and PostZon Data you need separate packs for each type of data.

   [What is Internal Use, Web use, Full, Thoroughfare and PostZon Data?]

These packages expire after 12 months, but if you buy multiple packages then they used consecutively after they each expire.  Or in other words if you buy 2 packages then the second will only expire 12 months after the date it actually first got used or when the credits are all used up.
