Hi Julius!
You can do this, although it’s slightly complicated. That statement & functionality is in the file woocommerce/includes/class-wc-cart.php — specifically, at line 919:
// Force quantity to 1 if sold individually and check for existing item in cart
if ( $product_data->is_sold_individually() ) {
$quantity = apply_filters( 'woocommerce_add_to_cart_sold_individually_quantity', 1, $quantity, $product_id, $variation_id, $cart_item_data );
$in_cart_quantity = $cart_item_key ? $this->cart_contents[ $cart_item_key ]['quantity'] : 0;
if ( $in_cart_quantity > 0 ) {
throw new Exception( sprintf( '<a href="%s" class="button wc-forward">%s</a> %s', wc_get_cart_url(), __( 'View Cart', 'woocommerce' ), sprintf( __( 'You cannot add another "%s" to your cart.', 'woocommerce' ), $product_data->get_title() ) ) );
}
}
That is where the behavior around that action occurs, and is where you’d insert any other behavior you wanted (such as redirecting to the checkout page).

Thanks D Smith,
I will try to play around with it.
My other option is to empty the cart once any page loads or visited.
I tried to use this function, I found in the web.
add_action( 'init', 'woocommerce_clear_cart_url' );
function woocommerce_clear_cart_url() {
global $woocommerce;
if ( isset( $_GET['empty-cart'] ) ) {
$woocommerce->cart->empty_cart();
}
}
However, the code above only triggers when you visit the homepage. For some instance I used a function is_page() but it seems doesn’t to work.
Anyone had the same experience? Any advice would be appreciated.
Thanks
