You have to buy twelve bottles at at least £80
but seriously, what is the catch? If i do this what do i have to spend?
As far as I am aware you spend what you like, cases of wine start from as little as £60 (probably cost them about £30), but beware once you sign up they will inundate you with sales literature. Its a loss leader, if only 50% of those who sign up go on to buy more, they make a profit
Sorry forgot to mention , I used a voucher last year and got 12 bottles a very drinkable wine for £20, have managed so far to resist buying anymore despite all the sales literature.
