how do you process payments?
garethr: Paypal is good and pretty feature rich, but it's not the most straightforward thing to work with. It's not really that the API is under-documented, more that it can involve lots of back and forth and your code needs to deal with lots of cases. The advantage is ease of use. In terms of time to implement and wide spread user awareness it's a good starting point to get the money coming in - with more options provided as time permits.
