Free standing nail polish diy for cheap

Where we can get this for cheap or virtually Free :

I am always trying to find new ways to organize my nail polishes since my collection is ever growing and I can't help myself when I see all the pretty bottles neatly placed in the salons.... I just want to take it all home. 

I have always admired all the lovely nail polish wall mount displays that nail salons have. It is so practical and at the same time an absolute piece of art. The only thing stopping me from covering my walls with those is the ridiculous price. It is way way way way..................... out of my budget as their price of around $70USD which hold around 100 polishes. I have over 400+ bottles now and I am not ready to dish out almost $300USD for a display. 

So the crafty diy part of me has been thinking for a while where on earth can I get something that can hold a lot of polishes for cheap. Then when I went grocery shopping one day I saw the perfect thing. I saw those card dis that kinda looked like this one

I was thinking this is perfect, free standing so I don't need to drill any holes in the wall and it already has those steps so I can neatly put all my nail polishes in place... the only problem was that it was still filled with merchandise and was sure the grocery store would not give it to me without selling all those cards.

For the rest of that week, I would search high and low at all the grocery and convenient stores I visited to see if they had any empty displays. 

Then I finally found an empty Cadbury Chocolate display. With a few touch ups (mostly just wrapping the background with patterned scotch tape). Although I know that this still won't come close to holding all my polishes, but I now at least have something to look at > < It was so exciting. 

As a bonus I was always able to reuse this display and keep it from going into the dump. REUSE REDUCE and RECYCLE.
