This is about what I'm into it for...this includes pretty much everything from top to bottom film, frame, baseboards, beds and ground covering. The things in BOLD are what I ordered online, everything else I got from Lowes/Home depot. So it was about $650 plus another $100 with tax/shipping added.... plus I had to get stuff like extra screws and staples maybe another $20. Roughly about $850. Of course if you didn't want to do beds and just grow in the ground or if you already have containers that you are going to use then you could chop like $300 off that cause you wouldn't need the wood for the beds or the ground covering. So for just the base, frame and film it would be $300-400, which for a 12x12 greenhouse, I wasn't able to find a kit anywhere near that price. And if I wanted to make it bigger I could just get another hoop and ground poles for $30 and add 4 feet on the back if I want. I plan to add some extra stuff to it like thermostat controlled exhaust fan and vents which will be another $300....that would bring me up to around $1000 total. Which still is about half of the price of any greenhouse kit this size with all of those features.
