Right now I am currently a Tradebit member and want to test ejunkie out and if it is everything I think it is I will be making the full transition of migrating all my goods from Tradebit to ejunkie.Since I have just started my trial I still want my Tradebit to work however in the PayPal IPN field there is only room for one IPN URL.Is there a way to
have two coincide for the time being?

We don't require you to enter our URL in your PayPal account. Our buttons already take care of that.
