I think you'll see that you can save some money. I have mentioned the malt prices at Brew & Grow (for full sacks) and LP can deliver sacks to my house for less (quite a bit less). I *did* get a sack of Weyerman Barke Pils from What's Brewing in Palatine for $64 which I thought was excellent for a local place. But I just paid $48 for Swaen Pils and $50 for Swaen Pale Ale. I think you'll like it.
On top of saving money (which is crucial), I think that even if i broke even in shopping at my LHBS vs. online, the convenience of having grain shipped right to my garage door is more than worth it.
No more fighting traffic to get to the LHBS, navigating the zoo of people that always seem to be there when I can make it in, waiting forever to weigh out my own grains (last time I was there, they had one (1!) scale to serve the gaggle of customers there to weigh out grain) and then checkout, lugging them out to the car, navigating traffic back home, then lugging them down the stairs to my basement.
Yeah, screw that noise.
