I see quite a few people say they use Paypal for intangible items (things that you cannot touch, SEO packages). You may be interested to read the following - Paypal "......our purchase protection is now being extended to intangible items and services. You should be prepared to provide ?compelling evidence? that you provided the intangible or virtual item or service, should a buyer dispute a transaction. Compelling evidence includes any evidence available to prove the buyer received the goods or services, or benefitted from the transaction. Examples include proof the buyer accessed your site or downloaded a file, and/or relevant portions of terms and conditions to which the buyer agreed. Although Purchase Protection will now extend coverage to buyers for intangible items, Seller Protection won?t apply to intangible items. However, having proper proof of delivery can help a seller win a buyer?s purchase protection claim" Just a heads up for anyone who has not seen this.
