After putting in a £30 order and expecting 38.5% cashback, I got a measly £6.60. The Quidco form to fix this required a reference number, which Gousto hadn't supplied. Quidco support wouldn't help without it. I emailed Gousto, but couldn't believe their response: they refused to provide me with a reference number, and stated 'we do not have any offers associated with Quidco.' Alarm bells!!!
In addition, my Gousto box was a mess. A pack of green beans had split all over the bottom of the box, combining itself with loose stock cubes, spices, and apples, and a sachet of sesame oil had exploded over it all. I'd lifted out the chilled part of the order without realising, so dripped sesame oil onto my new dining room carpet. It still won't come out and stinks to high heaven. I'd never order again, even if it was free.
