I can't remember but am I right that there's an overlap between last year's promo and this year's? I wonder if that will have an impact on how speedily DSC post.
There is.
The promotional period from last year's offer goes until 19FEB18, and the start of the promotional period for this year is 12FEB18.
If they have some way of "switching off" the vouchers, are they going to do that now and potentially affect those who still have legitimate bookings as per last year's T&C?
