Yes, I got the email too. I will watch the WBTC site for any clearance deals.
The groceries site if fine by me, you can order single bottles and juggle deals and vouchers, I've been doing this for the last year or two.
I'll never forget the amount of free wine I got from their Wine Club site, also sadly now closed. One Christmas I received a full case (12 bottles) of their leading Xmas wine, port and fizz included. I was selected to review the case, and boy did I enjoy that task! Oh how I miss that site
