Why am I paying for return shipping on a product that was no where near the description? I lost alot of valuable time purchasing waiting on item to arrive when I finally do I receive something totally different it was a remote controlled automorph optimus prime toy only to get a cheap knock off that doesnt move remotely & is not even battery operated or even has the same name as ad where I purchased from and now I have to dispute it on paypal to get my refund now this? To pay for returnshipping?

In the event of a dispute you need to bear in mind possible return trackable costs before you buy from that seller / item / country.

Paypal state this >>
PayPal is not obliged to reimburse you for any costs that you incur to comply with any of PayPal’s requests for cooperation for the purpose of resolving the problem (including, without limitation, costs that you incur to return a SNAD item to the Payment Recipient or another party as PayPal requests), although sometimes it may reimburse these costs.

Although they will compensate you for some of the cost if you have activated this at some point before you made that transaction .....

You also have the option to do a chargeback via your card issuer instead of a Paypal dispute if you funded your Paypal payment via a credit card.
