More often, if a product is obviously defective, or the wrong item was shipped, they may say just keep it (or throw it away) and send a replacement or refund.

More often, if a product is obviously defective, or the wrong item was shipped, they may say just keep it (or throw it away) and send a replacement or refund. I've had this happen with multiple companies. (Wrong t-shirt, warranty replacements on some items, credit card extended warranties, a couple of ebay sellers where the item was defective, etc.) Definitely something I wouldn't abuse, and I hope others don't abuse, because it increases the efficiency of the system - both by reducing impediments to buying things and by reducing overall cost when things go wrong.
