To receive 1000 extra Clubcard points with your August statement, you must register online with the Clubcard linked to your Healthy Living Club membership and spend £50 or more on groceries on your first shop at tesco.com/superstore. Offer valid on deliveries ... to 8/5/05. Excludes tobacco products and infant milk formulae. Purchases from the Tesco. com Extra sites do not qualify. Offer valid only for recipients of this mailing.

I am assuming that by 'groceries' they include everything you can buy in the grocery section of the Tesco site for home delivery - including phones!
