This method was the earliest of those adopted and remains the most popular.   You simply look for sellers that allow you make a cash deposit at the bank of your choice (you don’t need to have an account with that bank) and place your order.  The seller will then provide the account information you need to go to the teller with cash and make the deposit into their account.  The cash will be available in their account instantly and upon uploading a copy of the receipt through LocalBitcoins “Attach Document” feature, below the message box, the seller will then verify the details and release your bitcoins from escrow.
