The Method Grid store is where you can find pre-developed grids ready to be downloaded to your main account grid library.

As at current release, the store only holds free-to-download grids. In the future, we envisage this store hosting grids for sale (single payment) thus allowing for grid developers to trade their intellectual property. 

Account architects can effectively download (or "clone") grids from the store to their account grid library page. Once in your account's grid library, architects and builders can edit the grid and all its contents as per normal.
