This came up in a casual game with a friend last night. He is the runner with an economy based upon the The Supplier. One turn he hosted a Data Folding on it. At the start of his turn the "start of turn" effects trigger, and since it is his turn he picks the order. He claimed he could have the supplier resolve first, and then still get the money off the newly in play Data Folding. This didn't seem right to me as Data Folding wasn't in play when the "start of turn" effects triggered.
Who is correct?
What about a similar situation. He already has a data folding in play and wants to use the "start of turn" credit from it to pay for something else already hosted on the supplier. Is this allowed?
