we,d all like to do that, but sometimes the economics of it all far outweighs whats best,...as..it always boils down to how much is this going to cost....its ok if the store is close by, but, if its a good distance away, then your time, fuel costs have to be factored in...mind you..you pay a pittance for your gas...so maybe travelling is ok...but..if you had to pay $10+ a gal, then ..somehow i think your fingers would be doing the driving....
