Sorry to hear that. I've used the treat code every week since then (that'll be about 6 or 7 times by now) and it's worked every time in the self-scan big panel readers. I missed out this week though because all the coupons had gone. Not that that would have mattered much because by Thursday afternoon our Sainsburys had run out of them anyway! I've only just twigged that you have to CLAIM your treat early on in the process so you get one allocated, but it mustn't be activated until you are within an hour of being able to use it at the scanner or it will expire. I haven't quite worked out exactly how far you have to go in the claim process to secure the voucher for yourself without actually activating it, it's quite confusing, I'm old, I could do with a sequence of screenshots to show me how far to go to secure the coupon but not activate it, hahahha! The FAQ is quite confusing too.
