title: Different Sales Tax for different locations of same country in Magento
body: <p>Hi I need to set the tax rule in Magento by following the below conditions.
   All purchases shipped to California, but outside of San Diego, are charged the same rate, which is 7.25%.
   All purchases shipped to San Diego (part of the state of California) are charged the rates enclosed in the spreadsheet.
   Most of the rates are 7.75%, but some are different.</p>
  
  <ol>
  <li>Examples (All purchases shipped to California, but outside of San Diego)
  product1 $24.95
  Shipping &amp; Handling $4.95
  Sub Total $29.90
  Sales Tax (7.25%) $2.17
  Total $32.07</li>
  <li>Examples - All purchases shipped to San Diego (part of the state of California) Shipped to Coronado, California
  product1 $24.95
  Shipping &amp; Handling $4.95
  Sub Total $29.90
  Sales Tax (7.75%) $2.32
  Total $32.22</li>
  <li>Examples - All purchases shipped to outside of the state of California
  product1 $24.95
  Shipping &amp; Handling $4.95
  Sub Total $29.90
  Sales Tax (0%) $0
  Total $29.90</li>
  </ol>
  
  <p>Shall I need to make 3 different Rules for above 3 cases in Magento administrators panel under
  Sales->Tax->Manage Tax Zone Rates  or defining only one rule is enough?</p>
