They give you tracking information. Last time I ordered from them, I gave them the wrong address, didn't realize it until the package was returned because of that, and the replacement they sent still got to me within a week or so of the original order. And I live on the opposite side of the country.
If you want them to hold your package for you, talk to your post office. Or your neighbors There are plenty of options for avoiding the situation where your stuff sits on your doorstep for a long time and gets stolen or damaged.
