How long does a buyer have to request a return after an item is delivered?

[comics-scifi-collectibles]

@frictionhouse   30 days from the date of delivery on eBay.

However if they paid using PayPal at checkout then they can file a PayPal return request for an item that is not as described up to 180 days from the date of sale.
