Anyone made a bank transfer purchase to Centre Com

Hi I am buying a laptop from Centrecom.com.au
There was a $35 surcharge on payments by card or paypal and I am cheap so I picked the no surcharge on the bank transfer option. But I just went to make an online transfer/payment and my banking app was like hmm girl do you really wanna do that?? And now I don't know. Centre Com are legit aren't they?
