I really wish there was a non-rush way to order with a guaranteed delivery moment. Usually I'm not in a huge hurry, and I would happily wait a few days extra if it means workers don't have to pee in a bottle during their night shift. However, a "3-5 days" delivery means there's a pretty decent chance I won't be home and have to go to the other side of town to pick it up - and that's incredibly annoying. So I end up choosing next-day delivery and order it when I know I'll be home the next day. Why can't I just place an order on Monday with a guaranteed delivery on Saturday? Ordering on Friday with a guaranteed delivery on Saturday is already possible, so what's stopping them?
