Study: Long Lines Mean Fewer Sales and Customers

Dallas A survey of 13,000 shoppers by M/A/R/C Research found that 10% of shoppers would leave a checkout line if the wait were longer than four minutes.

About 43% of those surveyed said long lines affect their decision to shop a particular retailer in the future.

In addition, about 3% said they would stop visiting the store altogether.

"Retailers really have to focus on keeping their wait times under 4 minutes with the negative impact of even one minute more," said Tony Amador, senior VP at M/A/R/C Research.
