When total price is above $200 cart price rule is applied and free products are added to the cart.
when total price is below $200, cart price rule is applied and free products are removed from the cart after we decrease quantity and click update cart button. But the minicart count doesnt decrease.
The items are being removed through the 'sales_quote_save_after' event and observer:
