Found 25th Nov 2017
Received an email from Nationwide about £10 cashback. Decided to check it out and also found the 50% OFF automatically added at checkout.
There is also a possibility of £6.30 from TopCashBack for new Gousto customers and £0.52 for existing Gousto customers.
Ordered the above 2 meals, effectively spend 5.88 after Nationwide cashback.
Didn't see TopCashBack Gousto offer before ordering, I would have made some profit...
