If there's no volume discount, does buying in bulk still make sense?
I agree with Rich Seller.  Avoiding a trip to the store is a benefit.  Not only do you save the time and hassle, but there's real money saved if a car trip is avoided: I maintain a spreadsheet for all of my car expenses – depreciation, maintenance, insurance, license & registration, gas, etc. Combined with starting & ending odometer readings for the year, I can see exactly what it costs me to drive one kilometre.  Granted, some costs are fixed simply by virtue of having the car, but gasoline is a variable cost avoided when a trip is avoided.
