The best thing about COD is that it's an online marketplace, which means that you don't need to set up a physical store or a physical office to start selling. You just need to create an account and start selling. And you can sell to as many people as you want, you don't need to worry about delivery or about having to stock products.

And you can get an immediate no-payment cashback on your first order, which means you don't need to wait for a payment to be processed.

So, if you want to start your own business, the COD system is definitely the best way to do it.
