Get free delivery at the moment with Laithwaites. This applies to all cases over £49.99 but for some reason it doesn't give the free delivery unless you do a couple of things. I'll explain below.
Couple this with one of the £25 off vouchers and you can get a nice crate of wine pretty cheap.
I went for this one as the Black Stump is lovely.http://www.laithwaites.co.uk/article~otbprefix~article_~id~M2660001~brand~LAIT~cid~SEARCH|GOOGLE|PL48~mscssid~05177F70533E4567818CB0342CD9ADEB.aspx

Add the case of 15 bottles to your basket. Then go and choose a higher value case (£69.99 or above). add that to your basket. review your basket and remove the 15 bottles.
proceed to checkout. New customers will have to register now and existing customers log in. Review the order. Delivery should show up as free.
Proceed to the payment screen and use one of the attached vouchers. I went for the 'winedeal' one. You should see £25 off then.
That's it. A nice case of wine delivered for about £45.
Worth noting for new customers that Quidco are giving £11 cashback at the mo.
