Poor user.....
I am no longer a paid-member here, so I'll have to use the public reply.
I talked to my friend a day or two ago, and he's done $70,000 gross so far this year, selling those greenhouse kits. Not bad for a home business. Says he's also busy with local farmer's market sales. Surprising that in a slow-economy, people will pay so much for decorative plants.
Making those greenhouses is so simple. You can buy a bender for $35 (somebody invented a real cheap solution to that). The rest is just done with an abrasive cut-off saw and a very cheap bench drill press.
Craigslist.com ad costs him nothing. His front door is his cell phone. It's a real sweet business, if you can manage it.
