I received this offer from Blackmores. Hopefully it works and isn't targetted. Says you have to be a Blackmores member however I'm not certain you have to be.
After I signed up it says my expiry in my account is 12 December 2021 (under Blackmore's period) and I didn't have to enter any payment details.
3 months free membership to 28 by Sam Wood.
The offer is available for first time 28 by Sam Wood members only. The offer cannot be used in conjunction with any other offer. Receive three months of 28 by Sam Wood at no cost from date of sign up. Sign up between 13 September 2021 and 23 September 2021. Must be a Blackmores member.
i got in without a Blackmores membership or entering in payment details, thanks OP
