I bought a very nice item at a garage sale.
I then put it on Craigslist for profit. I sold it for about 5 times what I paid for it.
One man kept emailing me and was quite rude. He kept saying, "Why don't you tell me where you got this?" and then when I was vague, he wrote, "Why don't you tell me where you really got this?"
I am quite sure he was the owner of the garage sale.
I just kept responding with, "Are you interested in buying? If so, let me know."
What I did was not unethical, but he obviously was upset about it.
Now, the absolute truth is that I was excited to get the item for myself, but after trying it out realized it was not going to work for my needs and knew I could sell it for far more than I purchased it for.
