For in-stock, Prime-eligible, fulfilled-by-Amazon products the delivery has nothing to do with the seller. The shipping vendor (to me) is Amazon, the warehousing vendor is also Amazon, and they're using the typical UPS, USPS, and sometimes FedEx suppliers. I'm choosing between pictures, descriptions, and reviews of products on Amazon. In that context, the individual seller (and there might be a dozen for an individual product, though typically only one marked Prime) has nothing to do with the delivery, and it's a question of the quality of the actual product. For what it's worth, I have Prime, live on the end of a private cul-de-sac and have zero problems with package theft, typically filter by Prime-eligible products, and have bought thousands of dollars of stuff on Amazon. I can think of two instances where the products didn't get to me, and one of those was an exception to my Prime-eligible filter. The other time, I waited a week for my 2-day shipping, contacted Amazon, and they shipped a second unit. A couple days after the second unit arrived, the original also made its way to me at the end of a long, tortured journey through the wrong state, no idea what happened there (I contacted Amazon when it arrived and they said I could keep it...good service!)
