I wish it was only $800. It was $1800 for the bare shed delivered. I checked Menards and one about the same size was over $2000 for a kit you had to build. My shed is 8'X14'.
I guess things are cheaper around here, though I probably wouldn't want to work in the shed that $800 buys. Who knows, it might be cheaper to scratch up your own frame and clad it in tin.
Let's do some sloppy math:
An 8' x 14' (let's assume 8' high to the truss) shop would require around 30-40 2x4x8 boards for studs 16" O.C. and openings plus another 24 for the top and bottom sills if you lap the boards for the 14' walls. Then you need around 16 for the roof. Then you need 1/2" sheathing - around 12 sheets for the sides and 4-6 sheets for the roof. Then you need about 14 corrugated tin roof panels plus ridge cap. Add on 12 sheets of 4x9 ft hardie panel for siding. Lets throw in a standard 3-0 steel door.
Here's a cool roof rafter calculator:

I'm quoting local prices from home depot's website:
(82) 2x4x8 pressure treated pine: @ $3.97 per board = $325.54
(18) 4x8 1/2" 3 ply sheathing: @ $20.62 per board= $371.16
(14) 25x96 in corrugated tin panel

$12.39 per sheet = $173.46
(4) 4ft suntuf ridge cap: @ $15.98 per piece = $63.92
(12) 4x9 ft hardie panel siding: @ $23.88 per sheet = $286.56
(1) 36x80 in steel entry door: @ $100.30 per door = $100.30
That all comes to $1320.94 without fasteners, hinges, windows, storm clips, interior sheathing, insulation, wiring and fixtures, slab floor, waterproof membrane, hinges, liquid nails, trim or cauking. That also doesn't include cinder blocks or other foundation.
I would also note that an 8'x16' shop would get you the most bang for your materials because most sheets come in 4'x8' pieces, so that's 2 extra feet you're paying for anyway.
That also doesn't include the cost and hassle of getting all this to your front door. Boy, that $2000 kit is starting to look appealing! I kid; there's so many variables. I can totally understand someone wanting to get to work in there shop when they pay for it, rather than waiting until it's gathered and built.
