That is disgusting.
"My son has a rare illness and is on life support, and he is barely conscious, but every so often he whispers and asks me to lean in so he can tell me that his biggest dream during what little life he has left is to own a nicely presenting copy of New Mutants #89. I tell him 'Son, we just can't afford it, even though it's your greatest dream,' and a single tear runs down his pallid cheek just before he leans back and drifts to a fitful, despairing sleep. But now I see that you have a copy of New Mutants #98 that looks like it might be the bright light that puts a little joy into my son's heart during these dark days, and if only you'd drop the price a little, say 30 or 45 percent, I could afford to make my son's remaining moments of his spirit-crushing existence a tiny bit less tragic. What say you?"
Tell him you will deliver the comic in person for free to the child at the hospital. You want to meet the kid and tell him how brave he is, and give him another full stack of comics to read.
THAT would have been hilarious.
