If you want vinyl signs check out http://yardsignwholesale.com/ This site was posted here a couple of week ago by one of the board members.($1.50 a sign) That is the rock bottum price you will find on the internet. The18x12 are cheaper and work just as well. Put out 25 a week and your phone will ring. Remember as Chris said less is better! That's print, not the other thing!
This price does not include the stakes. Add the stakes in and they are more expensive than AGE Graphics.
