Product review (1 stars): Incorrect tax and second billing
You posted a second billing after the transaction was finalized.  It appears you charged me 8.3% tax.  We live in an unincorporated portion of Pinal Co. and our tax rate is 5.6%  I don't know where you come off charging 8.3% and doing it on a second invoice.  Your initial tax calculation was 6.7% which is also too high.  You have just lost a long time Amazon customer.
