Online is online. I'm sure my mother's used cheque before, but that takes long!
You can use PayPal for most things. You can also use a credit card.

Don't worry about it too much. Look how many people buy online and do banking. As long as the site is not a dodgy one, you will be alright.

And if for some reason somebody got your card number, all you do is tell the bank, they will cancel your card and you get a new one.
