You may restrict your search to vendors within a Geographical Radius.
To do this, specify either a City/State combination or a ZIP Code and then
select a distance. The center point of the city or zipcode will be considered
point zero and all vendors within the distance specified will be returned
in distance order.
If you select "only international vendors", then the radius search will be
ignored. If you specify only a state, then all vendors in the specified
state will be returned but the radius search will be ignored. If you specify
a zipcode with no distance or a distance with a city but no state, then the
radius search will be ignored.
