Even big box store don't return merchandise to mfg..be it defective or not....knew someone who worked at two different big box hardware/everything type store warehouses where these things are brought....all gets crunched, baled or whatever and sent to recyclers, dumps, who knows, but not back to mfg for credit to company.....guess the original cost is low enough to balance the loss....don't understand it, but that's big business......and if employee takes anything...and is caught...instant dismissal.......some stuff is still good, customer just decided not wanted........go figure.....just like restuarants, donut shops, all chain foods, etc., leftovers are tossed into dumpsters...and we have poor, hungry people in this country....too bad, so sad..
