Yes i does as it provides more variety and feature already highlighted.

Yes it has a huge impact on sales. Not just the display itself but its placement also has an impact on sales e.g. shops often place chocolates, candy, batteries etc near the cash counters to encourage impulse buying. Additionally if a display stands out a customer is more likely to purchase.

Yes it does if you done it correctly with strong branding and a concept which educate the customer about the USP's
