National Retail Supply They send products you never order and charge extremelly high prices. Con artists! PITTSBURG, Pennsylvania

They called my business, saying that my order is ready to ship (!!!) and they need to confirm shipping address. Unsuspecting employee confirmed address, and I received some credit card supplies (rolls of thermal paper). Although I get those supplies from my local bank, free of charge, I can buy them from local office supply, at least ten times cheaper than the price National Retail Supply asks for! For 24 rolls they want $180.00!!! Local store wants $18.00!
I called them and they said that I don't have to keep the supplies if I don't want them, and send them back to them at... my shipping expense! I told them that I'm not under any obligation to do that and if they don't pick them up within 30 days I will throw them in the garbage.
They are con artists!
