I don't like creating new accounts to purchase addon but I think the pain is worth it. Developers in general has to pay a hefty 20% ~ 35% of sales commission to these retailer. Then their is local government tax on top of that. Margin for these product are razor thin. I was able to pay with Paypal so I have no concern about security. Since they have done a fantastic job to delivery this aircraft, I am willing to overlook this inconvenience.
