cloudy brainiac is 19*0.9 so 17.1 after overpay but he also added a steaming conq which make this ~17.8. :P brainiac price is 4 months old though, but this sale happened 3 months ago so this price should be fine for it.

You also forgot 2 bills and 20 uc ducks (2 keys each) which is ~2.5 buds, on top of the 20.3 buds for the unusuals (if you are doing average value *0.9 as the only right overpay method). So 22.8. Resuggest at 17.8-22.8 please and do better backpack checks next time. ;)
