Paypal and allopass info

Up until recently we didnt have any form of online pay service that was easy to use, so paypal and allopass are new to me. Can anyone tell me what can i do with those in terms of buying games online (and their monthly sub if it has one).

PayPal is fairly simple to use. When purchasing something if the site has an option to use it, then you can. Buying games online with Paypal is no different then using anything else.
