T post spread on me and freeze and thaw cycles compromise my limited cribbing skills. I just taper the stacks and reuse the pallets.
Here are a few of our sheds.... Built this 2 cord shed with 8- 50x50 pallets, 3x4 runners under pallets, 2x6 uptight supports, 2x4 cross pieces in Dec '15. Got it full with the roof on. Stack is 54x52x94... this is our big shed, 7'wX 6.5'hX14'l...it holds 5 cords. Pallet with scrap plywood on floor. both ends of the big shed... Good view of a single shed...4- 50x50 pallets, 6' wide roof. Holds 1.25 cords stacked full. This shed is 5x10'. Floor was a equipment pallet, Sides are one row of 48x48 pallets and top row is pallets cut in half... I hope these last a long time.
This is what I'm doing. Two pieces of rebar mesh easily bend and connect together to make a 1/2 cord crate. Or use some spare boards to make crates.
