Global promotions site, Groupon, was forced to close a Marks & Spencer deal a day earlier than planned after 100,000 vouchers were sold within 24 hours of it going live on the website.
The offer was for a £10 M&S gift card for a payment of £5, meaning that the high street retailer will be giving away some £500,000 worth of products.
A spokesman for Groupon told the Telegraph that the company saw the promotion as a “great success”.
He added: “Our mission is to deliver the best deals for the things our customers want, I dare say there will be a few people getting barbecues planned this weekend now.”
