How do I handle "Showrooming" in a retail case interview?

Suggest omnichannel integration: dynamic digital pricing matches in physical store apps, or enable in-store sales associates to order out-of-stock items online with home delivery, keeping the transaction inside the client's ecosystem.

What is a typical margin range for specialized apparel vs grocery retail?

Specialty apparel yields gross margins of 50-60% and operating margins of 10-15%. Grocery has low margins (gross of 15-20%, operating of 1-3%), relying entirely on high velocity and extreme supply chain density.
