Street Sales

Step 1: How to Start
After obtaining your drugs, press F1 to open the radial menu and select "Corner Sell" to activate the sales.
Next, use your third-eye on local NPCs, whether they are walking or in vehicles. For vehicles, aim your third-eye at the bonnet to interact.
Step 2: Negotiating the Sale
Once the NPC has considered your offer, they will make a counteroffer. You can choose to accept or deny it.
Some NPCs may only accept a specific mixture of drugs, and some might even call the police.
Once you've either accepted or declined the offer, you're free to move on to the next sale.
Pricing:
Gang-branded drugs are worth more than regular drugs. Once a gang reaches a certain level within Vertex, they can brand their own drugs.
By checking your skills menu, you'll notice that each drug type has an XP level. The higher your XP level for a particular drug, the more it will affect the price when selling it.
Police:
Stay alert for the cops!
They may be surveilling you and taking photos of the deal as it happens. If the cops are called and they see you fleeing, they might chase you down and search you. Stay calm and avoid acting suspicious.
