Size Can you expand this?

So I went online and found a website that sells C&C cages with coroplast and everything... but it costs around $400 and that is WAY too expensive. So I went online and found Midwest cages, I've heard you can expand them so that sound good. I was wondering if you can expand this one: https://www.amazon.com/gp/aw/d/B001...199_img_2?ie=UTF8&refRID=0848RMQK17VHJDPJRQ7M

I was wondering because there was another Midwest cage that $55 dollars, on that one it had pictures of the cage expanded, but on this one it didn't, so I was wondering whether it was expandable.
