Have bought wines from these people many times - they're generally good quality.
I always use their "10% off voucher" which they email to you if you sign up for the newsletter.
The terms are "Please note this offer is only valid for 7 days and cannot be used in conjunction with any other offers. Only 1 promotional code can be used per order per person."
To me that reads that I can use it on every separate order I place. Which I have done.
However I have recently tried to use it again and have been told that I have used the voucher twice before, so it is no longer valid.
To me that is false and misleading advertising.
Should I report them?
Per order per person.
