...just add a delivery charge past your close-by cutoff point for free delivery. They can say yes or no then, you are right there on the phone with them, easy enough to quick whip out the google or yahoo or mapquest mapping thing. "Yes, ma'am, I have cords of wood for sale, where are you located, what town"? As soon as the customer says the town, you should have the page setup right there on your computer, type in the town or zipcode, mash enter, bam, a second later you have a driving distance from your yard. Anything past whatever you choose, say ten or fifteen miles, add a sum to that, whatever you think is fair, a buck a mile say.
Everyone today understands driving costs and fuel costs, if they don't, you really won't want them as a customer anyway, they will most likely give you grief on something else.
Back when I was working for some firewood folks, half their business was local, mostly word of mouth, the other half was oddly enough in your neck of the woods, delivering bundles to upscale apartments with fireplaces in beanerville. That paid quite well, like five times more than what selling by the cord did, because delivery was up to and including carrying bundles up elevators right into folks apartments. We wouldn't do *one* bundle, but if they took like at least five or so, we'd do it, just did a route around town and dropped them off. Gave us an excuse to go into boston and have some fun and have some cash when we got there as well....
