Best Buy isn't the only store that punishes shoppers for too many returns - these are all the companies that are tracking everything you return

Home Depot spokesman Stephen Holmes said the company uses The Retail Equation to combat return fraud, which he said is "believed to be feeding the opioid epidemic."

"And returns fraud is also often the work of organized retail crime rings, thus funding serious crimes," he added. "These efforts not only protect the retailer’s bottom line, but they also help protect the communities where we do business. "

Unlike many other retailers, Home Depot only tracks returns that are not accompanied by a receipt, he said.

"The good news is that it’s pretty easy to avoid a non-receipted return these days because we can look up any card transaction or customers can opt to receive an email receipt rather than try to keep up with paper," he said.

CVS said it partnered with The Retail Equation (or TRE) last year.

"TRE's return management services are utilized by several major retailers representing more than 34,000 retail locations in the US," CVS said. "Since implementing TRE’s solution last year, approximately .003% (or one-third of 1%) of returns have been declined at our stores."

A customer whose return has been declined can dispute the decision through TRE, which will then initiate a review process with CVS, the company added.

Sephora said it uses The Retail Equation, but only cracks down on customers with "excessive returns."

"We make every effort to accommodate returns, but a small fraction of customers take advantage of our policy, in many cases returning more than twice as much merchandise as they purchase," the company said. "This limits product selection and unfairly impacts other clients. When we identify excessive return patterns, we notify those customers that we may limit future returns or exchanges if no proof of purchase is provided."

Customers have complained on social media about Dick's use of The Retail Equation.

JCPenney confirmed to Business Insider that it uses The Retail Equation to help prevent "fraudulent or abusive returns."

"Use of this system does not impact the vast majority of day-to-day transactions," the company said.

Shoppers have complained online about being banned from returning items at Victoria's Secret. The retailer did not immediately respond to a request for comment.

Toys R Us confirmed that it uses The Retail Equation in a tweet to a customer earlier this month.

In a statement to The Wall Street Journal, a Best Buy spokesman apologized to anyone "inappropriately affected" by the policy.

"On very rare occasions — less than one tenth of one percent of returns — we stop what we believe is a fraudulent return," Jeff Haydock said. "Fraud is a real problem in retail, but if our systems aren't as good as they can be, we apologize to anyone inappropriately affected."
