2. Socks
Socks that rank second on our list of best selling products door-to-door are never enough. Even though they aren’t torn, one of them is missing; it’s like the ground has opened and swallowed it. You can start by selling socks because it isn’t that big investment and they are selling like crazy. Every person will buy a pair of socks if you show up to their doorstep because you will do them a favor and save them a trip to the store. Also, unlike other products, socks don’t have an expiration date which means your money won’t go to waste if you don’t sell them all in a short time.
