Quoted from NYP:Just a suggestion but maybe price the 3 ramps separately and don't sell them as a set. Then ignore the complaints, complaints go with the territory.
I think he is saying that the cost of materials is about the same regardless if he did the one big ramp or all 3. I don't think he could just sell the one ramp cheap out of a set and then get stuck with the other ramps that have less demand.
I would sell both the main ramp and the set. Put a note on the one ramp that it's expensive to make by itself and better deal to get all three ramps.
