Is it legal to buy a third-party warranty for a secondhand camera?

Question

I'm planning on buying a used camera on eBay that comes without a box or most of its accessories. I don't think it comes with a warranty. I noticed that eBay sells warranties for that specific model of camera. Is it perfectly fine to buy one, or is this kind of warranty black market?

Answer 1

Ask e-bay if they provide coverage for used items.
