How will it reduce costs? They will only have to file one sales tax instead of two and only have to know one set of rules. So yes they will save money. Also wholesalers will not have to worry about all the PST exemption documentations. PST audits and all that CRAP!! I suspect that some saving WILL be passed on as people will be hit by sticker shock and prices will have to be reduced. Overall I suspect it might be a good thing. Thousands of PST bureaucrats will probably lose their jobs. And thousands of businesses will eliminate one annoying and complex administrative task.
