Afternoon one, same again to all,
Brief question: Does selling additional products in the qame department reduce overall sales for the other products?
Ie. In an 100000 places Electronics only store selling TVs, fridges and phones with, say, 2000 sales for every product at a certain price, would introducing GPS navigators and thus increasing the choice of products have a negative effect on sales for the aforementioned 3 products?
Or is it only by increasing department numbers that you lose overall sales?
