eBay

Does ebay have any way to ensure that I am covered with replacement/exchange items?for instance if:the seller agrees but then doesn't send the replacement orthe replacement is damaged from mailing?

Hello,I bought a fragile item but it came damaged. The seller agreed to ship another one butwhat if the replacement is damaged again in shipping?Will it be covered by paypal? I'm trying to decide if I should just go for a refund or have a replacement...
