I have lawn signs for both my businesses that I got through Vistaprint and for FREE just paid shipping and handling ~ but definitely agree with Momof4 to check your bilaws about where you can place them on your property, size and so forth cause you do not want an attempt at advertizing to end up costing you more money in a fine

As for how 'effective' they ~ to be honest no one has ever said 'hey I saw your lawn sign and thought I would call you' HOWEVER I do get a lot of 'my friend told me about you' and well I do not know the friend or how they know me so perhaps the friend saw my sign or website or any of the other forms of advertizing?
