Well, what I did was; I went to www.local.com, chose a few choice fields and then I just started copying address into my notepad on my computer then I paste the names into Avery templates and printed. Local is a site that features local businesses and most of the ads were place by small business owners like us so I had a better chance of selecting businesses that could utilize my services.
The good thing is; I ordered 500 postcards so since my search was South of me next month I will do a search North of me. Then I will go East. That way they don't get the same postcard twice. When I'm out of those I will create a different design with another "special promotion" on them and start all over again. It only cost me about $70 for the 500 postcards that's including shipping.
