 So you can dupe almost any item in Cyberpunk 2077 post 1.6, this is how. So this works with any item you can stack, with a stack above 5 in your inventory find yourself a drop point on the map. Then guys simply sell all but one item you want to dupe to make sure you leave one in your inventory. Now you want to purchase all but two back from that drop point, so use the slider to make sure two are remaining in the drop point and here's where the glitch works. On xbox press x and a together to confirm the purchase, on playstation it's square and x to confirm the purchase. If done right you will purchase the items back from the drop point but they will still be there for you to buy back a gain doubling up on the initial number of said item you had in the first place and from here simply rinse and repeat guys and you are golden.
