Hi hj,
Thank you for your response and I apologize for my delayed reply. We dropped the project for awhile, but are revisiting it now. So if I am understanding you correctly, there is a way to hide pricing and manually approve users, but people who have not been approved can still view/use the 'add to cart' button and pricing in the cart?
We've looked into a couple of apps, but it doesn't look like we would be able to get one that does exactly what we want. We are in the medical field and can only sell to those that can provide us the correct credentials. We would LOVE to use Shopify, as it seems like a great e-commerce tool. We've got our website on Wordpress right now and there are too many things to update and keep track of.
If anyone can help us, it would be greatly appreciated.
