Every locality in Washington state potentially has a different sales tax rate. And, Washington just changed their rules so that the sales tax for instate merchants is not based on where the merchant is located, but where the customer is. So, for every small business that does any business other than through a physical storefront, they need to go based on (at the very minimum) the zipcode. (http://taxrates.dor.wa.gov).
ick, I edited out a clause - I was trying to say their are more than 50 values because of all the different rules and localities - learn to proof I guess.

And that's just Washington State.
