ATL welding supply is a bad business to order from.On Saturday Feb. 05/2011 I ordered a part from them online.I paid extra for USPS Express delivery because I needed the the part ASAP.Thurs.Feb.10/2011 the part hadn't arrived, I called ATL and they said they'd track it and call me back.When they hadn't called back, I sent them an email asking where my part was.I received a nasty e-mail from them telling me that since my order was small, they couldn't be bothered to track it.They also told me in the e-mail that my order wasn't worth their time to deal with and in the future to place high dollar orders if I wanted better service.It is now 2/13/2011 and still no part.I would reccommend not ordering from this company.
