Selling things from your web site, or e-commerce in geek-speak, doesn't have to be expensive and complicated. It's not necessary to go to the lengths of setting up an online shop if you want to sell just a few different products that don't change much. At its simplest, a few Paypal buttons will do the trick: see the implementation of simple paypal buttons on the hUJe site

Even simpler is a facility to accept donations via Paypal: see the implementation of a Paypal donation button on eolayokun.co.uk
