I very rarely return items, but received some DOA batteries from Amazon recently (for an Eve contact sensor - 1/2 AA batteries are a real pain to source).
I found the return process to be wildly low friction. I didn't have to print or package anything. I initiated the return, and the next day an Amazon delivery driver came to my door and I handed them the unlabelled pack of batteries.
