But...why the developer did not include a payment system of objects in ads? There is no automated system for users who intend to buy. It is a serious offense. There is only the opportunity to request money to advertisers but not to buyers. For a localized ad site it is not a problem but for an ad site on a large scale ... how user pay an object to advertiser without an automated system? Not all web users know how to use PayPal to request money and plus this is inconvenient and cumbersome.
