[H]Opening 4packs! Payday 2 and Payday The Heist[W]keys/ref + collateral

I have 3x Payday 2 and 4x Payday The Heist 4packs

For Payday 2 4pack I want 6,5 keys + 1,5 keys (6,5 keys collateral and 1,5 keys for actual game)

For Payday The Heist I want 2 keys + 6 ref (2 keys for collateral and 6 ref for actual game)

The Opening 4pack process is working like this:

1. I trade you 4pack for actual game price + collateral
2. You open a 4pack
3. We trade. You return 3 remaining copies and I return collateral keys
