Yes,auto part stores HAVE to mark up products to make 35-45%..they have a lot of expenses.Does WM make deliveries? NO. So,buy a little pickup,pay for insurance (expensive),gasoline,hire a driver,maintain it.....thats a lot of money.Now figure that most parts stores have 2-4 delivery vehicles...there's a huge tab right there.Not to mention to pay for the lights,heat,all the employees,their Workmens Comp,pay them for holidays/Vacations/Personal/Sick days,train them,stock the shelves (overhead),store and liability insurance....and still need to make a profit..Yes,thats why a $2.00 quart of oil is $3.00 or more by the time it gets to the shelf.Now...if that little parts store cant demand their own special pricing like a WM goliath can...there's a big reason why you pay $9.00 a quart for Mobil 1.
