TF2 Keys LOCK

You don't "need" to trade it daily. You want, tops.

1. Buy them in advance and keep your inventory stocked
2. Buy them from other people instead of Steam
3. Use gems instead

i like to buy them on dispanser.tf for bitcoin :)
no lock + cheaper :)

buy it from other people for paypal/btc/other kinds of payments
they're also cheaper than store and market, but be careful who you trade with

This title almost made me panic. Thought TF2 keys couldn't ever be traded anymore >.<

Key lock, kind of ironic when you think of it isn't it? But the lock is annoying but as others have said just buy in advance or trade for them

If you need to trade immediately just have the other person list a cheap item like a card or emoticon for the trading price, you buy it from them, give it back to them. Just like with trading anything else make sure they have good rep and are the right person, chat with them.

You can always use outside sites like tf2wh.com or tf2shop.net, both of which take credit cards. In the case of the Warehouse, you can also just trade in items to get credits to spend on keys or refined.
