I like it. Just got my 2012 Edge yesterday and was Googling solutions to managing that cavern of a bin. I will be building a shelf.
That coin holder is a joke! The edge is replacing my 1997 Grand Prix (yes, I have had it for over 15 years) which has a great coin holder. As luck would have it, it has slots in the back which fit perfectly into the grove in the side of the bin. I am keeping the 15 year old coin holder to use in my new edge. (see pictures)
