ultimately i think this all boils down to the OP's salesmanship....you could easily have a small banner displayed in your shop and perhaps have a price list for different sizes, gee, they cant afford the $45.00 banner, downsize them into another SMALLER SIZE. Tell them they can use it next year, and the year after that. You don't really need a year on it, hell count the damn candles!
Somehow the original idea is akin to throwing a $20 bill in the portable toilet cause you dropped a quarter in it....cause you damn well arent going in after a quarter. Losing out on dollar jobs to chase pennies....
