You do not need PayPal to "have". You do not need to install little program on your PC or something. If you choose PayPal you will be connected to your own bank. These ask for your login code, as usual. The amount will automatically be written off without you something to fill. Easy!
With a bank transfer payment and shipping takes a little longer. You will receive an invoice by e-mail sent to you to pay. We wait until then to send the amount to our account.
With Paypal you can simply through your e-mail address or you can pay Paypal also turn to your credit card to use (see www.paypal.co-uk).
