I've been thinking a lot about how to handle calculating FL sales tax. This is something that must be tackled. I checked on other ecommerce programs and it seems that most have a FL sales tax module.

There are approximately 1700 zip codes in FL and 67 counties. What is the best way to handle this in UC?

Logic: IF state="FL", when User Enters ZIP -> lookup county that zip is in -> Add county tax to 6% sales tax

Is it practical to create the table and populate 1700 records in a module .install file?

Would a FL tax module interface with, or replace, the tax module?

If we can figure out the best method to handle this I don't mind trying to implement the solution. I've never developed a module but I am armed with the Pro Drupal Development book .
