In Wisconsin, it's 5%. I guess it could be lots worse. Of course, counties can add a little if they want. Brown County (where Green Bay is), for example, just added .5% maybe a year or a year and a half ago to help pay for the renovation at Lambeau Field. There was quite an uproar from some people over adding the tax, but since the Pack is a publicly owned team, I don't have a problem with it. Of course, I don't live in Brown County, either /w3tcompact/icons/wink.gif (but we do do lots of shopping there).
