Where do you find this promo? I can only find, on their sports promotions, the early goal payout for the EURO 2020.
Just saw that they also boosted the formula 1 odds and there is already a first promotion regarding Wimbledon.
Check your mailbox, they have sent an email today about this promotion. Seems like this promotion is available for today's match only (Wales vs Denmark and Italy vs Austria). Place your bet on any of those team and Stake will refund your bet “if your selected team lose during extra time or penalties”. Check your mail to see full details.
Found it, thanks! Hopefully they repeat the promotion for tomorrow (Belgium vs Portugal). Always nice to have some extra insurance!
