I bought a 5l tub of Valspar paint today for £46. Just painted and absolutely hate the colour! It looks so different to photos I've seen online (more orange than pink). I know I should have done a tester. It says online you can buy a different colour and send both receipts to them and a pic for a refund but I'm worried about spending another £46 and not getting it back. Has anyone managed to get a refund this way? Thanks.
