So I get an email from our receptionist that I have a UPS package from BRS up front. I go get it and return to my desk and wondering what it could be because I didnt order anything from them aside from a couple odds and ends recently which I have already gotten. I open up the box and it's a gallon of BRS Bulk Magnesium Chloride. No invoice, no receipt....just the product. ??? I look back through my emails, invoices and statements to be sure that I didnt order it. Nope. I did receive an email about prizes for rating products but I have yet to rate anything. I can't access BRS to see if there was a promotional thing going on that if you purchase so much, you get this free. Anyone have any ideas?
