Wee3Bees, forget the goodwill. There is about as much honesty in the honey business as there is in gold bullion. Go for the 1.60 or no sale. It won't rot! When you run out there are plenty of them out there waiting to supply your customers, and when the producers are out of honey, there is little hope that anyone else will have an spare! And yes, if you ring them they will add on fifty cents. So if they ring you, add on fifty cents. It really is simple arithmetic, aye?
Your provisioning for your own faithful customers will pay off in the long run. A year is a long time, and a year without a crop is an eternity.
Cheers and good luck. If the first buyer doesn't want to buy it, the last one will!
