Ecommerce TAX

http://www.ecomorder.com/techref/taxship.asp?demo=tax An example that finds shipping rates online and calculates exact sales tax for addresses in the state of California. Just press the Update button to accept the "demo" address.

http://www.usps.gov/ncsc/ provides a service that returns the county and complete zip code for an address which could be used in tax calculations.
http://www2.taxware.com/taxcalc/index.asp provides a online tax calculator that will calculate exact sales taxes for free ten times after the merchant has filled out setup information. This could possibly be used to provide information for tax estimating by A) setting up an account for each store and B) doing full scale processing.
Independant Systems (www.taxrates.com), 1-630-858-4067, 1-888-844-4966 may be willing to price the tax rate database at a flat rate rather than per merchant.

miSim DE is an excellent, portable and powerful IDE for developing PIC applications.
The only consistant, simple to use yet powerful development environment. It simulates real-world devices via virtual component "plugins" (LED,LCD,key,motor,TV,etc) in real time, has a syntax highlighting editor, macro assembler and disassembler. Regular updates and third-party plugins keep this software ahead of any other PIC IDE.
