Will I get my clickbank account band by purchasing a product from my own affiliate link?
I've done it several times over the years with no problems. Of course make sure you use a different email address than the one you have as your listed email address with cb just to be safe.
Don't worry ... I am also purchasing ....
It is perfectly legitimate to purchase through your own affiliate links. But ClickBank does not allow you to withdraw affiliate earnings until there are 5 unique purchases through your affiliate link (and you have to get the other four now!).
