1. I can select both cod in shipping method stage and Credit card at the time of Payment information ideally it should not.
2. If we update the qty, at the time of cart. Price should update automatically. We have to use update cart button to correct the payment. And even if customer fails to use update cart the qty is not updated at final billing.
3. We need to have an option next to out of stock tab saying that notify me. So that customer will get automatic notification when products comes in stock.
4. Kindly link the "Grab it" to the check-out page don’t link it to the cart.
