I want to buy strange weapons for metal, how do I buy Stranges?

This is the strange weapons page. Scroll down a little and you'll see all the bots.

This is a bot. Click on it to see all the weapons it has.

Here you choose the weapons you want to buy. I've selected a Strange Pretty Boy's Pocket Pistol and a Strange Cleaner's Carbine.
To the left you can filter your weapons if you for example only want to see Engineer or Medic weapons. 
To the right you'll see how much you'll have to pay for the weapons.
Hit the green "Next Stage" button to continue

Now you'll see your backpack. Here you can choose if you want to trade your Strange weapons for the Strange weapons you selected before or if you want to pay with keys. I want to pay with metal so I don't select anything and hit the "Trade Now!" button.

You're now in the queue to buy the weapons you selected. You might be in a queue for a minute or so. 
You can see what the trade needs to look like. 2 Strange weapons for my 1 Refined and 2 Scrap metal.

Now this will pop up. Click the green "Go to trade offer"

You'll now get into a trade. Simply accept the trade if everything is alright.
When the offer is alright and has gone through then the trade will be closed.

You'll now see this. You now have the weapons you wanted. Simply close it by clicking the white X at the top right of the box.

You've now succesfully completed a Strange weapons trade! Congratulations!
It's basically the same with all the other trades, but. You can always go and check those tutorials as well.

I want to sell Stranges for metal, how do I sell my Strange items?

This is the weapons page. Click on the "Sell Stranges" button to begin.

Here you choose the Stranges you want to sell. I've selected a Pretty Boy's Pocket Pistol.
To the left you can filter your weapons if you for example only want to see Scout or Demoman weapons. 
To the right you'll see how much you'll get for your Stranges.
Hit the green "Trade Now!" button to continue

You're now in the queue to sell your Stranges. You can see the queue at the top of the screen. I'm currently in a "global queue" which is what you'll be in at the start. Then you'll be assigned to a bot to trade with it. You might be in a queue for a minute or so. 
You can see what the trade needs to look like. 1 Reclaimed metal for my Pretty Boy's Pocket Pistol.

Now this will pop up. Click the green "Go to trade offer"

You'll now get into a trade. Simply accept the trade if everything is alright.
When the offer is alright and has gone through then the trade will be closed.

You'll now see this. You now have your metal. Simply close it by clicking the white X at the top right of the box.

You've now succesfully sold your Stranges! Congratulations!

Yes and no. Our bots will offer you a higher price for said strange item if it has any strange parts attached to it, but the price difference will not be much. On the other hand, we do not offer any extras when said item has been killstreakified.

Remember that we will not accept your refund request if you are unhappy with the price that the bot offered and that you ACCEPTED.

The bots set an item as overstocked when they reach 15 units of said strange weapon. This means that if the total of said strange weapon in all bots is 15, then we are not buying any more until we sell some.

You will have to wait until someone sells that specific item to the bot,as all of our bots are restocked by users like you.

You can also check the other banking types for your desired item (for example, if you are looking for rare hats or rare stranges, check out item banking)

Then you will have to wait until the bot gains more space by buying or selling (depending on what banking) items from/to the users. Staff will take action if it's needed, but we ask you to refrain from poking them about it every 5 minutes.

This happens when all of the bots from the banking which you are attempting to use are full, as we do not load the inventories of full bots in the general view. You will have to wait until they have more space in their inventory.
