I have a question regarding this mod. If I configure it by county and then handle any exceptions to city if any, how does Zen-cart and or the mod decide what county the address belongs to?
I'm in South Carolina and the state has a 6% rate. Some counties charge up to 2.5% and some cities within the county may have their own addition.
For example Myrtle Beach is in Horry County so the tax for Myrtle Beach would be:
State: 6%
Horry County 1%
Myrtle Beach 1%
Total tax 8%
Being the address only has city and zip code, how will the Zen-cart and module calculate the tax to the proper 8% being I do not see how it knows its Horry County?
On the other hand, can someone tell me how to configure this mod? Also do I need to install the addressbookzone validation sql script or is it totally optional?
