Why not just get a DIY cube? If you have access to a DIY core you might as well get the whole cube.
If you can insert your corners while your edges are already in place, your cube is too loose. That thing looks like it will pop if you look at it funny.
But then you have a really useless storebought that won't turn well unless you wear it in uber good. If you have a storebought and you're buying something from C4Y, then you might as well get the core along with it, since it's only $.99.

I might do it so I don't have to waste a DIY for my calendar cube and still make it easy to turn, but shipping is more then a spare core so I'll wait for a big order
