To amend the Michigan Consumer Protection Act to prescribe detailed disclosures that “high-volume third-party sellers” (more than 200 'consumer product' sales in a year) would have to make to an online marketplace (like eBay) to disclose the seller's full name, full physical address, a working phone number and email address, whether the seller makes, imports or resells consumer products and more. The site would then have to post a phone number on the seller's offerings for reporting "suspicious marketplace activity." The bill is supported by broad coalition of large Michigan "brick and mortar" retailers.
