Two suggestions
Or you can read descriptions carefully before clicking the buttons.
In GW2, Trading Post plays you!
- - with the option to turn confirmations off – I HATE 4,011 prompts confirming what I just told the system to do… redesigned WvW menu, I’m looking at you.

The reason you need a confirmation on this is because if you do buy in error, they cannot refund you. It’s a one way street because it is considered an account upgrade and they cannot reverse it. With such a serious change, a confirmation should be added, especially with the names being very close to other options.
1.) I agree there should be a separate confirmation tab. The way it works right now is that in the event you spam the button (say you have a sticky key) you are in no luck. But at least when you have a separate confirmation window, you cannot accidently double click.
2.) Not really an issue, you just need to read the descriptions better.
