Hello. Just wondering whether this made a difference.

In the trading rules, it seems to state that Streetwise is used to sort the selling cost for illegal items and Negotiation is used for legal items. (page 150, selling illegal goods requires a streetwise roll)

Let us say that streetwise was used to find a contact to sell goods to (ilegally) but because your negotiation skill was higher you wanted to use that...what would you feel fair?

Negotiation is more upmarket and as such can't be used for illegal goods (as Streetwise is needed for deaing with criminal types)

Because negotiation and streetwise come at it different ways, using the wrong skill gives set back dice?

Negotiation works just fine (this is what I am hoping, it seems odd that negotiation would not work for criminal things....as a lot of the stuff involved deals with criminal stuff it would leave the negotiation skill rather limited and streetwise still has a lot of important bits such as locating people to buy and sell to, picking up rumours, finding people and selling illegal goods)

Because negotiation and streetwise come at it different ways, using the wrong skill gives set back dice?

I don't think that's really the case.

Also, I'd use Streetwise to find a fence, put on the right air so they'll deal with you instead of seeing you as a threat or possibly a rat. I'd use Negotiation to haggle the actual price.
