WotLK Do i need premium account to buy characters

[maja111]

Hello. I'd like to ask you:
1. if i need to have premium account to be able to buy characters via trade system?
2. If yes - is 1 coin donation enough or i need to donate at least 5 coins?

Thanks for help ;)

To access Trade section, you need Premium account. And to get Premium you need to donate at least 10 Euros (last time I've checked).
