Is it possible to upload a newer version of my product so that it replaces the old one without first deleting the old one. I am not sure if this is possible and if it is I would like to know how to go about it.
I am new to this, just started a few days ago, so please bear with me if this is rather obvious. I did check FAQ and Help, but was not able to find an answer to my problem.
I am not using a full-blown cart, but a Paypal button thing.
