I live on a street where many of the houses don't have numbers.

Because of this I stuck a post by my driveway and attached to that is one of these

My house is the only one on the road that has easy to read numbers that are approx. 4 inches high, and 4ft above the ground. I have it setup to be eye catching and no-one else ever seems to miss it.

Amazon still manages to not properly deliver my packages.

EDIT:

It is even worse when they fuck up at night because I live in a fairly rural area and it is the only light at the edge of the road. At night, thing should be impossible to miss.
