But, as always, the devil is in the details. It's is an incredibly complex process that, while holding great promise, comes with significant limitations and unknowns.

Sales taxes. The state sales tax rate in Iowa increased to 6% (from 5%) on July 1, 2008. Iowa also collects a corresponding use tax on out-of-state purchases. Local taxing jurisdictions also may impose a local option sales tax if approved by voters. This tax is imposed on the gross receipts from sales of tangible personal property.
Not all states have the same sales tax, or any at all. Iowa has a minimum of 6 percent at the state level, and then the level varies from town to town. Virginia has a flat general sales tax of 5 percent--4 percent for the state and 1 percent for the local municipality.
