Hi- I have set up some price groups, with different sets of products, it works great when I call signup.php like "..signup.php?price_group=281" and the right products show up for each price group. But if I just call signup.php like "..signup.php" then ALL my products show up, which I don't want because then, all my different pricing options and offers are exposed. I don't want that. I want only the offers for a specific price group to be visible. How can I make it so that a request to signup.php without any price_group, will not show the full product list?
