people here seem to be asking for something like paypal to pay with. I thought I would point out that click and buy is like paypal except its not owned by ebay. Its just a third party system many companies use third parties such as click and buy. I agree however that click and buy's service is quite poor compared to others, but SE have always used click and buy as a third party payment option, well for a long time anyway as that is what their online stores use.
