Complaint Review: National Retail Supply

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!
