PayPal is all about paying for stuff online, or taking payment, and they offer many ways and means of doing so. Paypal Payments Standard is one of these services, suitable for the smaller business. It integrates with your website to allow you to sell products, including a full shopping cart and many other powerful features and there's no need for you to acquire your own credit card processing "merchant account" from a bank. It's probably not suitable for a full-featured giftware site, for example, but if you just want to sell a few products from your website then it's more than adequate and comparatively hassle free.
