We didn't charge for it for YEARS, probably 20 years. Then we got the printer and charged first $4.95 then 2 years later $7.95. No one to my knowledge has EVER noticed or thought either price was expensive. If you would be the first florist in your area to get a printer, I would try to and then actively visit your funeral homes and either offer them a commission or discount to sell the flowers in a consult or refer you. When people see your ribbons vs stick on letters they will be very impressed. I recommend adding your logo in a small size at the end of every banner.
We have templates in Word we give with our printers, and you can easily add your logo the the end of each word doc... every common banner is set up as its own word doc in #9 and #40. That way they will hopefully call you, b/c you had the most impressive funeral work and ribbons.
