I just got an OTP package and all went well.

If the problem is theft by drivers, then the OTP is counter productive as it alerts the driver that this particular package contains a high value item, so they can easily swap it or fool the system.

Being patient is where it’s at. In any case, many sellers include the “free” shipping in their costs, so it’s not rare to find a say a $20 item with Prime for $215 plus $5 shipping with another seller.

Amazon often has free shipping over $25 so over the months we just slowly add items in our cart, then buy by just over $25 increments to get free shipping.
