The huge growth in the second-hand market has seen a surge in sales for disc repair specialists.
Total Disc Repair, whose machines are used by Asda among others, claims there are almost 5,000 of its devices on the market.
The spike in demand follows the need to clean recently traded-in discs.
But it's not all about supermarkets – the firm's clients now include pawnbrokers, online sellers, libraries, DVD rental firms and even police departments.
The growth of the pre-owned market has been phenomenal and the fact that our machines are helping so many people benefit from this boom is fantastic,” said TDR's MD Mel Stephenson.
We're continually looking at how we can help our customers benefit further; from finding ways to reduce costs which we can pass on, to producing tips to help customers get more from their machines or investing in raising awareness. It's a very exciting time.”
TDR has re-launched its website and has continued to promote disc repair.
The company says it will launch a customer rewards scheme in the New Year.
