not looking for games

The 5:1 list means you pick 5 sets from that list and you give me 1 key.
(it's not the game Skyrim but the set of cards of that game)
From the more expensive list you can pick a total of 1.80 worth of sets for a key

I don't have that many sets, and the rate 6,6:1 is too high, I can go up to 5.5:1 if you take more than 5

No.

i'll keep it in mind
