The devil's in the data. If they get too many returns, I'm sure they'll can the product. Amazon + analytics = megaprofit. At the scale of an individual buyer, some things they do can seem counterproductive. At the scale that they operate, though, reality can be very different. They're not hurting for profit, that's for sure.
Yeah, I know... economies of scale. I've had to try and explain this concept more than few times myself in threads like this one.
Here's an "Economies of Scale" example that I profited nicely from just recently... Last weekend I put in my bedroom
a brand-new 43" 4K TV. I made approx $320 on the deal, and my cost for the TV was approx $9 in fuel and less than an hour's labor.
How? I had a work order two weeks prior to assemble and wire up a media display for a trade show here in Houston; it was a two-trip ticket, hourly at a pretty good rate. My gross on the first trip was $320, parts/supplies provided by client. They even paid me mileage to pick up the TV from Fry's. The return trip was to unwire everything and dismantle the display (an MDF contraption that goes together like IKEA furniture) and stack it in the corner of the booth, then collect the electronics and return ship. I expected to be returning the TV as well; they gave instructions keep the box for shipment. All together, took less than an hour.
Then when I'm all done, my tech support agent gives me the option of getting paid for my time on the return trip and shipping the TV to them, or taking it home and closing the ticket for $0 labor; all they wanted back was the custom-flashed media player and game controller they'd sent out to me, all of which fit in a carton the size of a shoebox. Of course I took the latter option; they even paid my parking. He explained that it actually would cost them more to ship it back safely and inventory it and warehouse it than it cost them; they were, and I quote, "not interested in warehousing hundreds of TVs for the value of this single campaign."
The ironic part is... that TV replaced a 32" LG commercial display acquired similarly; as part of an e-Menu "equipment refresh" gig. I bought 6 such displays for $25 each from another client a couple years ago; still made a decent profit on the gig, kept one for the BR and sold the remaining units locally for $75 each in 2 days. Probably could've gotten more if I'd been willing to sit on them; but with a house full of children, I had no interest in warehousing 5 32" TVs for the value they represented...

I loathe commercial broadcast. As the name suggests, it exists to broadcast commercials; any actual content is just an afterthought.
