A few months ago I opened a Macquarie Bank account including Mastercard. I haven't used it yet. When I applied they gave me two account numbers. One number is for a 'savings account' and the other is a 'transaction account'.
I wasn't sure which account I should use to deposit money to online. But because I want to buy some items from Amazon USA I sent it the 'transaction' account.
Have I done the right thing?
Transaction account is for transactions. So yes.
