Extra amount deducted before placing the order


I have placed order #7341 and have chosen express checkout using paypal but the amount got immediately deducted (38€)before placing the order and when I ordered you deducted full amount (38€ +50€ delivery).

Please restate the extra amount deducted.

Also I wanted to add 2x square enclosure but I could not- appreciate if you can add them to the order.

Thank you in advance,
