Amazon Refund question!

For an item to be refunded it must sold by amazon and fulfilled by amazon, or can it be sold from a 3rd party and fulfilled by amazon?

Thanks

From talking to some of the refunders, they say it only really needs to be fulfilled by amazon.

Only needs to be fulfilled by amazon, in some cases it doesnt need to be both, but it requires more work

Best to do it fulfilled or dispatched by Amazon.

For double dips it has to be Dispatched by Amazon.

You can do it using A-Z claim however this rips off the seller directly who has complete access to your info and unlike Amazon may contact authorities (not what you want). For refunding, use 'Fulfilled by' 'Sold by' or 'Dispatched by' Amazon
