Singleton | Verify Customers
Verify all registered customers and allow or disallow them to see prices and "add to cart" buttons
Singleton | Verify Customers focuses on controlling access to pricing and product information. This is useful if you want to offer different pricing based on customer status (e.g., wholesale vs. retail) or restrict access to certain products, but it doesn't replace the core functionality of MS Custom SizePrice Calculator.
Best for merchants who need to control which customers see prices and 'add to cart' buttons.
