Scott Electric and its usadustguard.com division are liars and thieves (Ordered on usadustguard.com, credit card charged by Scott Electric). They will send you an invoice for your order showing $0 for shipping and then charge you whatever they want after the fact (also known as credit card fraud). They've since changed their website to just say shipping is additional (with no calculator to estimate, so they can still charge whatever they want!), but it used to say they would contact you before shipping IF there were any shipping fees. They charged me almost $13 for shipping on a ~$25 order, for already overpriced dust masks. I never would have paid that much if they would have told me, as their website stated, again my invoice they emailed me showed $0 for shipping. I contacted them multiple times and eventually Ted Segiel said he would refund my shipping charge. I never received a refund and have tried to contact him again and he does not respond. Do not do business with these liars and thieves! read more
