Just got an estimate for an all AMSOIL fluid change (motor/trans/diff) is this a good price?

Im not sure exactly which Mobil 1 that is, but I use the ESP in my Nissan and get a 5 liter bottle at Walmart for $28 - which comes out to less than $6 a quart.

The only time I go to WM is to buy this oil - because it`s so much less than anywhere else.

That`s the only time I go to WM too but all I do is take a picture of the product. Then I walk across the parking lot and have Auto Zone match the price collecting the bonus points for the purchase.
