About oscommerce and PayPal

[SimpleDomaining]

Hello. Little question for someone who use paypal.
The general question is how many different website stores can be sent to same paypal address using IPN and two different return pages?

and the explanation of my problem:

I have 1 program installed on website in root/events, that sells events and charges via paypal IPN. On this program instructions is written that paypal autoreturn should be OFF. Program sendscustomer to the paypal and after checkout comes to the main page of the website root/infdex.
On same website in root/store i have another programm installed, an oscommerce store that sells merchandise and charges via Paypal too. The question is which option i can use (website standard, IPN or what, and how) to autoreturn store customers to where oscommerce sends them back? hope question is explained understandable.
thanks.

if I understand the question right, why not just use a simple meta tag redirect and place it on top of the html page of the success page
