I used Beer-Wine.com this week and was very happy with the service and speed of the delivery. I put in a order for some liquid malt extract to test them out and 2 hours after I put in my order online I received a email that it had been shipped, received it on thursday. All this was with the cheapest shipping option. ~ crum
