If you are looking to buy CE/Lockboxes with real money then get this deal instead. You get more value than buying from spiral knights itself.
I have 5KE and 110kCR and many valuables such as 5 haunted aura and shadow key etc.....
Heres my inventory http://steamcommunity.com/id/forwardslashpro/inventory/#99900

As of the 15-24 of October Payday 2 downloadable content will have a drastic price drop, http://store.steampowered.com/app/218620/
in the image below I have listed the DLC that i am interested in.

Anything i marked in red I'm not interested in.
The green arrows mean those DLC take priority.
i wont be buying sound tracks.

Buying the priority ones only will add up to £13.52 or $20.92.
And if the rest are included it goes up a small margin.
You choose which option to trade and before you do you can check out my backpack.
I will take friend request on steam if you have questions or you list them here.

remember the deadline is 24th of October.]]

P.S Buying all DLC packs means you get more valuables in my inventory and buying only priority means some valuables will get left out in proportion to the price it costs.
