I had this once happen few years ago with university books. Got emailed that it was delivered but I didn’t receive it and was home all day. Got them the day after.
I ordered an expensive instrument, and they said it'd be delivered the week after Thanksgiving.
Got an email that it was delivered to my porch the day after Thanksgiving, when I was all the way across town.
I didn't want to leave a $1,300 lute on my doorstep for anyone to snatch, so I drove the hour home to secure it. It wasn't there after all, so I installed their stupid app and it told me it would be delivered next week.
One of the worst buying experiences I've ever had. 1/10, would not recommend.
I have one of these. And signs. The only way I’ve managed to get delivery drivers to use it is to actually point at it and ask them (nicely) when I’ve been in. Works until a new person does my area…
