I don't think any thinking adult could argue with combining all of your errands in one shopping trip.

I wonder, however, if it's as easy as taking your business to Alma. According to this Web site, gas today is a penny cheaper in Mt. Pleasant than it is in Alma and Ithaca. At least, as of the moment I checked it out (if gas explodes through the roof, don't shoot the messenger). I think the volatility of prices is just as pertinent as is picking the place generally with the lower prices.
