Team Fortress 2 Premium DLC?

Ingame item purchase does work...

Buy anything from the tf2 store you will get that!

Edit - if you buy from online store Link you will receive a cap
The store is under maintenance so try later and buy anything.

Upgrade to premium does the job, too. But better buy an item and it'll be activated.

I believe you have to pay $5 in the TF2 store ingame? I could be wrong

u need buy any item. example 0.49$
use trial use this item and u get -25% discount
0.36 need donate

I wrote a guide about it: http://steamcommunity.com/sharedfiles/filedetails/?id=149039697
Feel free to ask me if you still have questions.

Buy a 3 cent catapult, you can do that with steam wallet.

Worked perfect, thanks for your help :3
