"When a fast-food chain runs low on ingredients due to demand, it either means something has gone very wrong with the supply chain or something has gone very right with its marketing. The McDonald’s Travis Scott Meal revived the idea of everyone having a default McDonald’s order in a partnership which led to $50m in incremental sales and an ROI of $3.22 per $1 spent. It shows how to achieve maximum effectiveness from a celebrity tie-in."
