Mines showing £1.67 with the offer.....
If you can't see it on the page then it must be account specific. It's only on the original variant. edit - it's showing logged out. It's not the 1 time use 25% voucher that is account specific, as this one is reusable.
What voucher are you referring to please?
Yes I agree, I only buy when good deals on, got 3 that I purchased for around £1.50 each last year in the sales, using a tropical pineapple one atm which is really nice.
