If you are selling stuff, you might need paypal integration. For instance, let's say you have 10 products for sale. Will you create a different paypal buy button for each of them? Maybe. But what if you have 100? I can create a script that will select the product and its price and send it to paypal directly, without a button. All you need is a buy form where people select the product OR, a simple "buy now" link, if you are selling products individually. PM me if you are interested.
