Can anyone confirm to me that this plugin will prevent wholesale customers from being charged sales tax? I've read back through a large chunk of the 136 pages of comments, and didn't see that directly addressed. All my wholesale customers are local, so they will get charged sales tax if they order through zencart. Right now I'm having them call me and I do an invoice separately on my bookkeeping software, but I'd like to get it all into zencart if possible.
