As a bit of a thought experiment - I'm a nova-hot decker and I want to grab a Fairlight Excalibur from my girl, Becky 99. I've done a fair number of runs for her, so I'm sitting at a pretty respectable 4 loyalty. With her connection rating of 4, that means she rolls 12 dice to try to find me my next deck. She will always fail though, since it has an availability of 16 and therefore buys 4 hits and she can only buy 3 hits.
To make it possible for her to find it, I need to find a way to get more on her availability check. The way to do that is to spread more cash around - 25% of the item's cost per dice you want to add. So I can get her to be able to find it if I spend another 100% more on it.
Oh, and she's a Fixer, so I have a 10% markup.
That'll be a cool 1,728,825 nuyen to get my new deck and it will take a month. Ouch, that hurts. Let's see if we run it through Simon Andrews instead.
He has 5 Connection and 3 Loyalty. I'm still going to end up paying an additional 75% of the cost of the deck to give him enough dice to find my deck. So I'm still out 1,523,012 nuyen.
