I have used a lot of advertising in my business life. The costs are very high and take a big chunk out of profit.
Local TV. One AD 20 times per week for 3 months $5000.00. It does work but limited exposure.
Local paper One AD $1270.00 per month. Eighth page small circulation it does work how well ?
AFR eighth page size. I am afraid to ask. Not many readers anymore i suspect.
BIG looks like great value and good quality.
I am retired now but would love to know if it works.
Small business needs good affordable advertising.
Go BIG
