I've seen paypal refund even without the item being shipped back.paypal. but i think he knows that paypal will requir him to return the item first.
he sent me an email tittled "online lawsuit". in it, he basicly explains that he wants a refund for the batt but he is not willing to ship it back because its leaking....
i'll gladly refund him the money if he can proov his issues with the batt..
so beware.
