later I decided to add a second greenhouse, money was a bit short at the time so I looked around for something cheaper.
I saw one advertised at my workplace for £40.00 about $60.00 US, there was a snag
I had to dismantle it from site and move it home myself build some foundations for it and rebuild it in my garden, it was also too big for the space I had so I cut 2 feet off one end.The ground in my garden slopes 2 ways so building foundations caused its own problems, however if you are willing to put in the time and effort a greenhouse costing about 20% of a new one can be yours.

ok so there you are a 6 feet square greenhouse complete with base installed for less than £200 $300 no excuse for not having one now
other places to look for 2nd hand greenhouses are supermarket message boards and local papers.
