Various updates at Mals.
MALS-E UPDATE - COUNTY LEVEL TAX
February 2011: You can now specify a different tax amount for each zip code in a state. In the Mals-E Cart Setup, select 'Sales Tax' under 'Tax and shipping', and choose Option #6. Select your state from the drop down box, and enter Z under '% Rate'. Mals will automatically determine the county tax rate based on whatever zip code the customer enters, and apply the appropriate tax.
