                    'total' => $request->total[$i],
                ]
            );

        );

        $product =  Product::where('id', $request->product_id[$i])->first();
        $product->cartoon = $request->av_cartoon[$i];

        $qty =   ($request->av_cartoon  +  $request->cartoon) * $product->ppc; //math of total quantity
        $product->qty = $qty  - $request->qty[$id]; //then minus the existing qty from product qty
