In Schedule I, keeping up with your suppliers will help you secure drugs to create new mixes. Since the suppliers are friendly with you, you won’t have to pay for the stuff they offer immediately. Rather, you can take your time sending them the money, but this will rack up some interest free debt, which you then have to put up at a designated stash drop. The dead drop for the second supplier, Shirley Watts, is a bit difficult to find, so this guide is here to help you out in Schedule I.
Shirley Watts Stash Dead Drop Location Schedule I

The dead drop location for clearing off Shirley Watts’ debt is on the west face of the warehouse. If you haven’t been to the warehouse yet, just head south from the motel. There is a ramp leading down beside the Piss Hut liquor store. From there, head west down the alley, then turn south. You will spot some large dumpster bins on the left, and between them, just behind the hedge, is Shirley’s dead drop.
Shirley Watts Debt In Schedule I: How To Clear?
Shirley Watts will be your go-to contact to purchase Pseudo and create Crystal. Since this material is a bit pricey, you might want to hold off from paying full price till you get your returns. But occasionally, she will drop you a message to demand some money to keep the supplies flowing. If you have some cash to pay off, first, unlock your phone and send Shirley a text saying that you wish to pay off the debt.

To use the dead drop, just interact with the box to get the inventory slots. Drop your cash from your hotbar and place it into the stash slot. The amount you have to give will be reflected on the top, so you have to pay the full price. If you don’t have the required amount, you can exit and sell more drugs to get more cash. After dropping the money, press the Done button, and Shirley will send you a text saying she has received it.
