You may use the "Gift Option" in following URL (right side of the page).
It says "Buying Construct 2 for someone else? That's kind of you! Enter their details below to make sure it's issued in their name."
So with that Gift Option, you can ask someone to buy a Construct 2 license as a gift for your name. In that case, someone can pay for the license using his/her PayPal or Credit Card, but the license will be issued in your name.
