The shed arrived in four boxes. We wanted to make a slab for the shed to sit on and so were not able to start assembly right away. Unfortunately for us, we started after the 30 day return window and once we got to step two we discovered that all four corner pieces were bent inside the shipping box. While a quick fix would be to have new corner pieces sent out the only info I’m being told is that we’re outside of the return or replacement window. So my advice would be to make sure you assemble this as soon as it arrives in case you run into a similar issue so you aren’t wasting hundreds of dollars like us!
