How many bags of mortar do I need per number of 8x8x16 concrete blocks?

I want to build a small basement, know the number of blocks I will need
(around 800), but dont know how to determine the amount of mortar. *I
intend to buy raw mortar and add my own sand. *I'll just buy a truckload
of sand, which I assume should be more than enough, but how do I
determine the number of bags of mortar? *This is a rural area and I have
to drive 55 miles to get it at a reasonable price, so I want to be sure
I have enough. *I refuse to buy it locally and pay their outrageous
ripoff prices (for example, the blocks at the building center 55 miles
away are $.89 each, locally, they are $2.40 each).

Thanks

Better rething "getting it at a reasonable price". Unless you are
hauling with a semi, 800 blocks will reqwuite multiple trips with
whatever you haul with. The fuel cost will add up in a hurry. I had
my blocks used for the same purpose deliverred from 54 miles away all
in one trip and dropped right at the excavation.
IIRC the delivery charge was $1.00/mile (one way).

Why make your own mortar? You won't save much buy adding your own
sand (be sure it is "mason's sand).
The convenience alone is worth something. By the time you have laid a
couple hundred block you will kill for any way to save time and work.
BTDT.
