Ride-on tractor mower £34.99

Screwfix customers bagged lawnmowers, costly drills and other expensive hardware for just a fraction of their usual cost overnight after a price glitch on the website reduced the cost of everything to just £34.99.

Eagle-eyed shoppers who spotted the glitch put in their orders in the early hours of the morning, and chose 'click and collect' so they could pick up their goods with their local stores opened at 7am this morning.

One collected £1,130 worth of drills from their local store for just £139.96 – saving nearly £1,000. Another bought a ride-on tractor mower – which normally sells at £1,599.00. Another picked up a £200 multi-cutter for just £35.

Customers who have already received their goods will be able to keep them but the rest will be issued a refund. Some probably went on to flip it on eBay to make some easy money

Happy Testing!




  1. If asked, I say that the best bug I ever spotted was when I as on a consultancy with a travel agency. Their call centre booking software had a screen for adding extras to the booking – transfer fees, excess baggage, airport surcharges – that sort of thing.

    The call centre operative was asked to choose from a drop-down list of charges, and then insert the cost of the extra charge into a designated field. When they clicked OK, that cost went straight through onto the final invoice.

    But I found that if you entered the cost of the surcharge with a currency symbol, clicking OK wiped out the value entered and sent £0.00 to the invoice. The workflow only displayed the final value of the invoice to the operator, so they would never spot a zero value for surcharges. There was nothing on the page to indicate the currency, and although all the company’s business was UK-based, I could imagine a new user error or an odd new surcharge that was only quoted in local currency causing this mistake.

    And no customer would ever query an invoice that showed them being charged zero for something they’d expected to be charged for. Very good for encouraging repeat business, but only a detailed forensic audit would have revealed how much the company had lost over time.

      oooft, that sounds like a tough one. As I am early in my career and still in my first company, I am yet to experience something this. Most of what I’ve experienced had no monetary value so a client would find a bug and just raise it and we’d triage accordinly
