If there is an issue with the camera within 30 days, then we cover the shipping. If you just don’t want/like it, then buyer pays.
If there is an issue after 30 days, then it’s generally the buyer’s responsibility to cover the cost of shipping the item to us. We cover shipping of the fixed/replacement camera.
Yes, Amazon will cover the return shipping cost if there is an issue within 30 days, but they generally will not accept returns after that (I’m sure there are some exceptions). You will then deal directly with the seller.
